Before you undo my edit, please try to find any use of the word heat map, or heatmap before 1993. You will not find one, although the grid display certainly pre-existed. In 2002 or so, NeoVision prevailed in a lawsuit filed by Optimark Technologies over use of the word. NeoVision was later acquired, and the new owner, SS&C technologies let this valuable Trademark lapse!
