Title: Proxy argument

from the doc:

Improving load time on pages with many images
If you have just a few images on your page, the standard base URL https://chart.googleapis.com/chart should be fine. However, if you have many images, you can add a number 0-9 and a dot just before chart.apis.google.com. If you specify a different number for each image on your page, the browser will try to load more images simultaneously, rather than waiting to load them in sequence. However, you should only need this if you're loading perhaps five or more images on a page. For example:
http://0.chart.apis.google.com/chart?cht=...
http://1.chart.apis.google.com/chart?cht=...
http://2.chart.apis.google.com/chart?cht=...

Default to proxy = 0
