Generating a custom marker with canvas is handy when you want to change the marker size/color dynamically.
The following code snippet contains a 'createMarker' function that creates a canvas, draws the marker graphics and returns back the Data URL encoded version of that canvas which can be used as an input at the marker creation.
See the example below.
hey, thanks for this. i found it very helpful. i am designing a map site that uses markers to show rain totals for particular regions. This works great.
