I'm trying to make an overlay on google maps of all 88 Ohio
counties, each in a color that represents the number of
volunteers we have had signup fron that county. I have been
using this tutorial from Elliot Media Group and it works great
for ONE county:   The county boundary information is kept in a
separate file as the variable "rawData." I figure I would simply
add a variable for each county in the javascript file, BUT with
an added accompanying variable describing the color. (rawData1,
color1, rawData2, color2 etc).  My issue is how to build a FOR()
loop to go through each variable and render the overlay for each
county. In php I would make a dynamic variable name, but I have
looked around and arrays seem to be the javascript solution. Can
anyone help me? I'm a total newbie at this and I'm doing this
pro bono for a good cause. The code for this is below, but a lot
is gibberish to me. THANK YOU for any help you can give me!  var
currentOverlays = [];                 function loadMap(){
var myOptions = {                                         zoom:
