Förderband” mit d3.nest() bauen

var propertyNest = d3.nest()

d3.keys() einbauen um die Punkte am “Förderband” zu definieren, bei denen die Umformung eingreifen soll

  • die verschiedenen Monopoly-Farben sind in der Property “groups” eingebunden
propertyNest.key(function(d){return d.group})

Um d3.nest() zu aktivieren, müssen wir einen Einstiegspunkt definieren, praktisch die Stelle die oberhalb der keys liegt, aber unterhalb des data-Objektes

propertyNest.entries(data.properties)

Als Ergebnis erhalten wir 11 Objekte:
