Rendering a Google Chart based on a html table

[SuneR]

Hi,

Forgive my probably stupid question, I am quite new to google charts
and the Google Visualization API.

I am wondering if it is possible to render a piechart based on a html
table - or do I have to build the data in javascript?

I don't think so. You'll have to transform the table into JSON data table. It's not that complicated. You can go over the table as an XML element, or just go over the rows (as children of the table main element)

There is no explicit support for this.  I think there is a javascript module that someone wrote that does this (Google it), or you could use tools like jQuery to parse your table for data, but the general consensus is that it's better to get the data from the original source rather than pull it from HTML.

Hi,

Look at gvChart it's a plugin for jQuery, that uses Google Charts to create interactive visualization by using data from the HTML table tag.

The gvChart plugin is horrendously out of date, I would be rather surprised if anything in it worked properly any more.
