#            - To see the full code check out the [GitHub repo](https://github.com/discdiver/data-viz-streamlit).
#            - Plots are interactive where that's the default or easy to add.
#            - Plots that use MatPlotlib under the hood have fig and ax objects defined before the code shown.
#            - Lineplots should have sequence data, so I created a date index with a sequence of dates for them. 
#            - Where an axis label shows by default, I left it at is. Generally where it was missing, I added it.
#            - There are multiple ways to make some of these plots.
#            - You can choose to see two columns, but with a narrow screen this will switch to one column automatically.
#            - Python has many data visualization libraries. This gallery is not exhaustive. If you would like to add #code for another library, please submit a [pull request](https://github.com/discdiver/data-viz-streamlit).
 #           - For a larger tour of more plots, check out the [Python Graph #Gallery](https://www.python-graph-gallery.com/density-plot/) and [Python Plotting for Exploratory Data #Analysis](https://pythonplot.com/).
