You can create a "select" event handler to zoom by doing something like
this:
google.visualization.events.addListener(chart, 'select', function () {
var selection = chart.getSelection();
if (selection.length) {
var region = data.getValue(selection[0].row, 0);
// figure out the region code and resolution from your selected
region
options.resolution = /* resolution to draw at */;
options.region = /* region to draw */;
chart.draw(data, options);
}
});
