I’ve been playing around with the new Google Chart API, released earlier today. The API enables easy creation of charts, dynamically:
The Google Chart API returns a PNG-format image in response to a URL. Several types of image can be generated: line, bar, and pie charts for example. For each image type you can specify attributes such as size, colors, and labels.
My example is shown below. I can think of a lot more convenient methods of creating graphs, especially when chartable data is usually already in Excel or Numbers spreadsheets. Still, pretty fun to play around with – check out what Brian Suda makes of it, on 24ways.
