Next, we need to apply the xRange and the yRange to the coordinates to transform them into the plotting space and to draw a line across the plotting space.

First, weâll need some data to plot. We’ll be using d3.svg.line() to draw our line graph. If we set that data point as the highest point on the chart’s Y axis at 200px, then we can use the ratio of any value in our data set to 60 and multiply that by 200 to get the Y coordinate of all of our points.
