I am looking for some free javascript framework to implement nice heatmap chart. It should look something like D3 Heatmap. The problem is that it have to work in IE8 which do not support SVG. I googled for other libs, but found nothing suitable. The only thing which seems to work fine is jQuery Hottie, but its feature set is not sufficient, I need something more mature and bigger. Currently I am thinking about making my own solution using VML or plain tables and css.
So, is there any javascript libs for heatmaps which support Internet Explorer 8?
