right now there's three methods to adjust how far out a heatmap goes:

• heatmap.weightByAttribute
• heatmap.weightByAttributeScale
• heatmap.circles.blur

what's the best way to tweak the fall off of a data point? if we want to reduce the strength by, say, 20% should we have weightByAttribute return (d.val - (d.val*.2))?

Also, is there an easy way for a non-developer to try different fall off strengths? this is outside of the scope of MapTable, but some tips would be most welcome!

thanks!
