How to do it...

In this recipe, we will show how interpolation mode can be configured on an area generator. This way matching interpolated area can then be created with corresponding line:

 var width = 500, height = 500, margin = 30, x = d3.scale.linear() .domain([0, 10]) .range([margin, width - margin]), y = d3.scale.linear() .domain([0, 10]) .range([height - margin, margin]); var data = d3.range(11).map(function(i){ ...
