Thanks. That would be a nice feature. You may know this but the USNG (US
National Grid) is based on a 1000m x 1000m grid system. Allowing a grid to
be created automatically, at a user-defined dimension would provide data
visualization that would be less biased by size (e.g. western counties are
much larger than eastern counties and, therefore, produce more visual
impact even when they have the same value).
