The request is simply to provide the showLegend option that the prior Flash version provided. It might also be useful (in some cases) to allow the absolute values to be hidden.
Here's my rational. I like the Geochart and use it both in the traditional sense and in a non-traditional sense. Specifically, I use it in a traditional sense to display a spread of values (mapped to the min/max colors) but I also use it as a geo selector. In this case, I use only two values, zero and one and map them to gray and red respectively (so selectable geos show up as a dark grey and selected geos show up in red). I then add a selection handler that toggles the selection and also apply the selection through an outside filter selector menu so the Geochart reflects/reenforces the current geo filter selection even if it was selected using a different control. This works very well aside from the tool tip and legend. I can live with the tool tip which I use to suggest that the user can toggle a selection but it also displays 0 or 1 which might be confusing. More control over what is displayed in the tooltip would be welcome though. However, The legend is more problematic since it also shows the zero to one range and color range even though it's really a binary choice (the gradient is confusing for min/max spread of one). To avoid this, I'm currently applying a hack to hide the legend but porting the showLegend option would be a welcome addition and a simple fix. Either that or consider modifying the legend to switch to a non- gradient version if the difference is one (not sure how that would work esthetically though, haven't really tried to mock it up).
