It provides quick and interactive. It takes a data from dataset and calculates the start angle and end angle for each wedge of the. Let yScale d3 scaleLinear domaind3extentdatamapd.
We will have to create two axes so we need to have two scales for two axes.

Because coordinates on a computer screen begin with 00 at the top left corner the bottom of our chart will have the maximum y-value and the top of the chart will have the minimum. Here we first specify the data we will be using in our line graph as the arrays data1 and data2.
