This chart is misleading. At a glance, viewers will presume that the chart shows that the overall number of Republicans making local posts was greater than Democrats, when in fact, it was simply the case that Republicans had a few more individuals making a high number of local posts (above 0.80). Be careful about this. You need to clear this up and/or use a different chart for the dataset before you put this in your portfolio. It should probably be a map or scatter plot, based on the numbers.
Also, these bars aren't user-friendly. The slivers are way too small to get any meaningful visual insights and/or hover over for tooltips. Many users won't even realize that the bars are made up of slivers with tooltip info available on each one.
