This visualization presents 2015 corporate tax rates for countries around the world as a horizontal bar chart. Each bar’s length represents the tax rate percentage, with color encoding from light yellow to dark green. Clicking a bar opens a detailed pop-up footnote explaining the country’s tax structure, and clicking again closes it. The chart uses D3 v3 with an SVG rendering, a linear color scale, and an ordinal y-axis for country names. Data comes from KPMG’s corporate tax rates table. Countries without tax data are assigned zero-width bars, which makes their detail pop-ups inaccessible until a solution is implemented.
