Add hvPlot

[MarcSkovMadsen]

I would like to suggest adding hvPlot to pythonplot.com.

hvPlot is unique in the way that it works on many, many data sources in a way very much like Pandas .plot. In addition it can output to both Bokeh, Matplotlib and Plotly by changing a setting. Furthermore it provides a lot of really powerful features like .interactive that makes your dataframe interactive with widgets.

If the interest is there, I would be willing to contribute some examples.
