Create a hexbin grid with equal-area and equilateral hexagons

Using hexbin grids is a great way to aggregate data. However, with the commonly used Web Mercator projection, it is impossible to balance the technical necessity of uniform area across all of the hexbins with the aesthetics of equilateralness for each hexbin in the grid. You can have one or the other, but not both. You'll need to use a different projection to help generate an appropriate compromise between the area and shape of hexbins. This walk-thru is meant to show how to make a map of Lexington, KY with equal-area hexbins. In particular, it explains how to create hexbins that are not only equal-area, but also equilateral.
