Add charts & plots support

[NabiKAZ]

Thanks for great project.

Can use graphical chart and plot in the Jupyter-PHP be like matplotlib and Plotly library of jupyter python? For example include Google Charts, chartjs, highcharts,... projects.

In other words, what is the equivalent of the following python commands in Jupyter-PHP?

import matplotlib.pyplot as plt
%matplotlib inline
plt.bar(range(0, 5), [10, 5, 13, 1, 20])
