D3 Examples - radar chart for nested data

radar chart for nested data

this version loads nested data from data.json:

index.html

//Load the data and Call function to draw the Radar chart d3.json("data.json", function(error, data){ RadarChart(".radarChart", data, radarChartOptions); });

then, it converts the nested data into an array of values arrays:

radarChart.js

// convert the nested data passed in // into an array of values arrays data = data.map(function(d) { return d.values })
