k - cool, to answer #58's question, "what's the best way to tweak the fall off of a data point? " you added colorStrength, gotcha. I loaded up dev-58 branch and played with the value. Setting it to 0 and I still saw colors - I would have expected none. Setting it to 1000 I would have expected it to cover the globe, but it only goes about say...45 degrees or so. The difference between 1 and 0.5 seems too small as well.

Either way - be sure to update README.md. I may actually be using it wrong as I don't know what the readme would say ;)

@Ths2-9Y-LqJt6 I just updated the behavior to make it easier to configure

• heatmap.colorStrength: (float, default: 1) Adjusts heatmap color strength, (0 make things transparent, 1 normal behavior, > 1 to make the color darker)

i had to merge master to dev-58 to get it to compile. testing colorStrength does not do anything. values of 0,1 or 10 load the same map. maybe commits from PR #56 broke this PR?

@Ths2-9Y-LqJt6 Since you merged dev-56 to master, I set the base branch for this PR as master.
That's surprising, I just launched the /heatmap.html example and colorStrenght seems to have an effect:

@melalj - agreed - it does work! I must have not pulled latest code. Thanks very for re-testing and sending along the screen shot of the different values for me to easily test against.
