The Bokeh examples below go through [hvPlot](https://hvplot.holoviz.org/), which adds an `.hvplot` accessor to data frames that deliberately echoes the pandas `.plot` API, so most of these plots are one call with a few keyword arguments. hvPlot has no regression line or loess smoother, so those two examples are missing. I provide hvPlot examples rendered as static images.
