Can python generate graph?

To generate graphs in Python you will need a library called Matplotlib. It helps in visualizing your data and makes it easier for you to see the relationship between different variables. Before starting with the graph, it is important to first understand Matplotlib and its functions in Python.

Can we extract data from graph?

The extraction of data from images is called digitization. The simplest process works by defining the range of data within a plot and calculating the value of the points on a plotted line within it. To do this we can make use of the WebPlotDigitizer (WPD).
