Created by Splunk4Good and spun off as a side project from the Clinton vs Trump: A Splunk analysis on the independent expenditures from the 2016 presidential election page.
Updated d3 from v4 to v5. From their README:
"D3 no longer provides the d3.schemeCategory20* categorical color schemes. These twenty-color schemes were flawed because their grouped design could falsely imply relationships in the data: a shared hue can imply that the encoded data are part of a group (a super-category), while relative lightness can imply order. Instead, D3 now includes d3-scale-chromatic, which implements excellent schemes from ColorBrewer, including categorical, diverging, sequential single-hue and sequential multi-hue schemes. These schemes are available in both discrete and continuous variants."
Therefore many of the outer color rings colors from previous versions are no longer valid! If you see a completely black outer ring, then please choose a new color scheme under ("Miscellaneous") or use the default schemeCategory10 by removing the <option name="viz_halo.halo.outer_colors"> line in Simple XML.
