    1. To understand the High Line’s effect on surrounding property prices, we analysed publicly available valuation data from NYC’s Department of Finance, and cross-referenced it with property sales data for blocks and individual plots (a detailed methodology is available 👉 here). This meant we could track how the values of surrounding properties have changed since the High Line’s arrival.What’s interesting is that if we group the properties in bands roughly one kilometre wide from the High Line you start to see that between 2007 (when construction started) and 2018 (when the data ends), properties closer to the High Line experienced a greater value increase on average than those further away. So the mean property value uplift for houses within 1km of the High Line was actually 92% more than the Manhattan mean. Or to put it another way — if you owned an apartment in that 1km, you earned on average about $67,000 a year from the uplift alone. 🤑

    1. Avoiding complicated outlining or mind-mapping software saves a bunch of mouse clicks or dreaming up complicated visualizations (it helps if you are a linear thinker).

      Hmm. I'm not sure I agree with this thought/sentiment (though it's hard to tell since it's an incomplete sentence). I think visualizations and mind-mapping software might be an even better way to go, in terms of efficiency of editing (since they are specialized for the task), enjoyment of use, etc.

      The main thing text files have going for them is flexibility, portability, client-neutrality, the ability to get started right now without researching and evaluating a zillion competing GUI app alternatives.

Unique graphical attributes can be applied to both quantitative data (such as temperature, price, or speed) and qualitative data (such as categories, flavors, or expressions). These attributes include:ShapeColorSizeAreaVolumeLengthAnglePosition DirectionDensityExpressing multiple attributesMultiple visual treatments can be applied to more than one aspect of a data point. For example, a bar color can represent a category, while a bar’s length can express a value (like population size). Shape can be used to represent qualitative data. In this chart, each category is represented by a specific shape (circles, squares, and triangles), which makes it easy to compare data both within a specific range or against other categories.

      This is an interesting fact, usually when I think of visualization and data I go to the classic default charts and data. I'll have to keep this iin mind.

    1. To help us get better comprehension of the structure of an argument, we can also call forth a schematic or graphical display

      I might be getting ahead of what's to come, since I am annotating as I am reading, but this gets me thinking about some visualization approaches I saw in the 1990s by the brilliant and forgotten Roy Stringer working on what he called "Navihedra" - while they were often seen as navigational, his ideas seemed to be rooted in better representations of the kinds of structures Engelbart is telling us

      In brief, however, Navihedra are 3D models based on Platonic solids and relationships between pieces of information are articulated in terms of the spatial relationships represented by the vertices of the polyhedron. That is, units of information (of any kind, media, size or complexity) are attached to a specific vertex and bi-directionally hyperlinked to all the immediately adjacent vertices. The overall structure being determined by some perceived relevance reflected in proximity. Proximate vertices are understood to locate units of information/argument that are more closely related to one another than units of information that are not directly hyperlinked. Furthermore, this 3 dimensional arrangement can be rotated in space so that differing patterns of inter-relatedness can be viewed. Creating such an arrangement is much more difficult than it might appear and requires an author to consider the structure/presentation of even a simple argument like the one contained in this article with at least as much care as a more conventional presentation.

      Sadly these were produced in a media form hardly displayable now (Macromedia Shockwave), remnants are in the Internet Archive.

    1. Nyhan and Reifler also found that presenting challenging information in a chart or graph tends to reduce disconfirmation bias. The researchers concluded that the decreased ambiguity of graphical information (as opposed to text) makes it harder for test subjects to question or argue against the content of the chart.

      Amazingly important double-edged finding for discussions of data visualization!

    3. Local Explanation Methods for Deep Neural Networks Lack Sensitivity to Parameter Values

      This paper shows that local explanations for DNNs with random-initialized weights are qualitatively and quantitatively similar to explanations produced by DNNs with learned weights.

      • Pros:

      The paper is clear, the problem is well stated and the method is sound.

      • Cons:

      The impact of the findings in this paper is unclear. Perhaps the most important point made in the paper is the importance of the architecture over fine-tuning of the weights for explanation tasks (and more in general).

      En los eventos locales se toman fotos durante el evento, al margen de los resultados. En el Data Week en cambio, las fotos con pocas en comparación (a veces nulas), particularmente en consideración a la privacidad. La lógica del espectáculo/impacto está más centrada en las visualizaciones mismas.

    1. That “hackers” can model beneficial process disrupts the often presumed subversive nature of hacking as much as it does easy assumptions about a Foucaultian notion of governmentality. Prototypes act as working evidence to lobby for changing government process, particularly those that improve digital infrastructure or direct communication with citizens. The capa-bility of code to act as a persuasive argument has long been noted, and modeling can produce charged debates about the very meaning of “civic.”

      [...] On a level of hackathons, prototypes can be speculative (Lodato and DiSalvo, in press) rather than an “outcome,” revealing conflicting notions of “civic tech” (Shaw, 2014).

      Nuestro enfoque ha estado centrado más en la modelación, que es requerida para la visualización, pero también en la idea de construir capacidad en la infraestructura y en la comunidad, lo cual va más allá del prototipo volátil, que se abandona después.

    1. sites such as Facebook and Twitter automatically and continuously refresh the page; it’s impossible to get to the bottom of the feed.

      Well is not. A scrapping web technique used for the Data Selfies project goes to the end of the scrolling page for Twitter (after almost scrolling 3k tweets), which is useful for certain valid users of scrapping (like overwatch of political discourse on twitter).

      So, can be infinite scrolling be useful, but not allowed by default on this social networks. Could we change the way information is visualized to get an overview of it instead of being focused on small details all the time in an infitite scroll tread mill.

    1. If efficiency incentives and tools have been effective for utilities, manufacturers, and designers, what about for end users? One concern I’ve always had is that most people have no idea where their energy goes, so any attempt to conserve is like optimizing a program without a profiler.
    2. This is aimed at people in the tech industry, and is more about what you can do with your career than at a hackathon. I’m not going to discuss policy and regulation, although they’re no less important than technological innovation. A good way to think about it, via Saul Griffith, is that it’s the role of technologists to create options for policy-makers.

      Nice to see this conversation happening between technology and broader socio-political problems so explicit in Bret's discourse.

      What we're doing in fact is enabling this conversation between technologist and policy-makers first, and we're highlighting it via hackathon/workshops, but not reducing it only to what happens there (an interesting critique to the techno-solutionism hackathon is here), using the feedback loops in social networks, but with an intention of mobilizing a setup that goes beyond. One example is our twitter data selfies (picture/link below). The necesity of addressing urgent problem that involve techno-socio-political complex entanglements is more felt in the Global South.

    1. Also, the more complex a software project becomes, the more work you have to put into and it grows exponentially. So, keep it simple and make it fast. It's much easier to write software, throw it away and start over again quickly, than having this huge generic system that tries to do everything. It doesn't make sense. It's just too much work. You'd get this huge software system with thousand dependencies and, in the end, it's really hard to innovate, get new stuff in there, or, the worst case, to change the concept. Almost every software that we have published is not generic but is used only for one case. So, keep it simple and get a prototype in under three days.

      Agile visualization its a worthy exception to this trend. It is generic while being flexible and moldable. My first projects start with an easy prototype in a week and became full projects in a couple of months average. Then I can reuse the visual components by using abstraction and making visual builders.

      The couple of months average included the learning of the programming language and environment, the data cleaning and completion. With the builders the time has started to decrease exponentially.

    2. What type of team do you need to create these visualisations? 
OpenDataCity has a special team of really high-level nerds. Experts on hardware, servers, software development, web design, user experience and so on. I contribute the more mathematical view on the data. But usually a project is done by just one person, who is chief and developer, and the others help him or her. So, it's not like a group project. Usually, it's a single person and a lot of help. That makes it definitely faster, than having a big team and a lot of meetings.

      This strengths the idea that data visualization is a field where a personal approach is still viable, as is shown also by a lot of individuals that are highly valuated as data visualizers.
