A scatter plot or scatter graph is another common type of diagram used to display data points on Cartesian coordinates with two different variables. Scatter plot is especially useful when exploring the problem of clustering and classification. In this recipe, we will learn how to implement a multi-series scatter plot chart in D3.

A scatter plot is another chart which uses Cartesian coordinates. Thus, a large part of its implementation is very similar to the charts we have introduced so far, therefore the code concerning peripheral graphical elements are again omitted to save space in this book. Please review the companion code for the complete implementation.
