Creating a line chart


Line chart is a common, basic chart type that is widely used in many fields. This chart consists of a series of data points connected by straight line segments. A line chart is also typically bordered by two perpendicular axes: the x axis and y axis. In this recipe, we will see how this basic chart can be implemented using D3 as a reusable JavaScript object that can be configured to display multiple data series on a different scale. Along with that we will also show the technique of implementing a dynamic multi-data-series update with animation.
