Bonus chart! Sunburst radial partition joy!


Oh, you thought we were done? Let's squeeze one more chart out of d3-hierarchy before moving on.

If you remember, the partition chart was a bit funky, largely because it's mainly used in datasets where only the leaf nodes (that is, the outermost nodes without children) have a value. Since some of the parents in our dataset have screentime values, this sort of distorts it and makes it look odd. We will re-render that, but make it all cool and circular this time.

You know the drill. main.js:

westerosChart.init('radialPartition', 'data/GoT-lineages-screentimes.json');

In chapter6/index.js:

westerosChart.radialPartition = function RadialPartition(_data) { 
  const data = getMajorHouses(_data)
     .map((d, i, a) => Object.assign(d, {
       screentime: a.filter(v =>
         v.fatherLabel === d.itemLabel).length ? 0 : d.screentime,
     })   );

};

We start by creating a radius that...
