Gradient Map

[JasonLin43212]

• [x] Color the map based on democracy score type and year

• [x] Fix the range of D3's scaleLinear for each particular score type

  • [x] Maybe look at VDem's guide to find more information about the ranges and create a hard coded object that maps score types to their min and max
  • It should look something like:

    {
    "v2x_polyarchy" : {
    "min" : 0,
    "max" : 1,
    },
    ... 
    }

• [x] Add in D3 transitions when the state is changed to slowly transition the colors instead of having it change suddenly

Currently working on it in branch heat_map_colors

Some of the score types don't seem to have a numerical range or are not available in guidebook.
