Hello,

I am plotting a rectangular grid where the axis labels are factors. If there are duplicated factors along any axis, as expected, an error should be raised. When I run my code I see:

ERROR:bokeh.core.validation.check:E-1019 (DUPLICATE_FACTORS): FactorRange must specify a unique list of categorical factors for an axis: duplicate factors found: 'a'

If I set BOKEH_STRICT=1 I

Today I was checking out the library and MSVC warns for https://github.com/alandefreitas/matplotplusplus/blob/359a775710e1b1fd5667281a0855806f149b7ab0/source/matplot/util/contourc.cpp#L1771

BOUNDARY_S returns a bool do the expression is bool > 0

Plotly already handles exporting plots as png.

At the moment, the whole plotly bar that normally shows at the top of each plot has been disabled.
We should re-enable it but only keeping the save plot image button.

I believe the API is stable enough to begin documenting in roxygen and also in other supplementary materials, such as vignettes and articles.

For instance should it be called Mortality Rate, or Known Mortality Rate? Each of the labels should have a tooltip perhaps explaining in a bit more detail, but every page should list not only sources, but how we arrived at the data (or link to a "Methodology" page)
