Hi, I'm trying (and failing) to use Google's visualization code to create an interactive map. When I hover the mouse over a U.S. state, I'd like the numerical value to be formatted to include a dollar sign. Here's my map code, could someone please tell me what I'm doing wrong? Also, if I've reached this forum in error, and there's a better place to ask for code help, could you point me in the right direction? Thanks!

[ICODE]function drawVisualization() {
var data = google.visualization.arrayToDataTable([
['State', 'Dollars'],
['US-IL', 200],
['US-IN', 300],
['US-AL', 200],
['US-AZ', 800],

]);

var geochart = new google.visualization.GeoChart(
document.getElementById('visualization'));
geochart.draw(data, {width: 556, height: 347, region: "US", resolution: "provinces"});
}
