5Python-nvd3 is a Python wrapper for NVD3 graph library. 

6NVD3 is an attempt to build re-usable charts and chart components 

7for d3.js without taking away the power that d3.js gives you.

18 A scatter plot or scattergraph is a type of mathematical diagram using Cartesian 

19 coordinates to display values for two variables for a set of data. 

20 The data is displayed as a collection of points, each having the value of one variable 

21 determining the position on the horizontal axis and the value of the other variable 

22 determining the position on the vertical axis.
