This is a simple pie chart
Google offers Webmasters an easy solution to create simple or and quite complex graphs in the Google Chart API section of the Developers Guide. It is quite simple to use, if you want to create an image such as above, just link to the following image:
]http://chart.apis.google.com/chart?cht=p3&chd=t:60,40&chs=250x100&chl=Pie|Not%20Pie
Google will then do the graphical generation stuff; here is a quick overview of the URL structure (key -> value):
- cht – What type of chart you want:
- p3 – 3d pie chart
- p – 2D chart
- v – Venn diagram
- s – Scatter Plot
- lc – Line Chart
- bhs – Horizontal Bar Chart
- chd – The Chart Data
- Separated by commas, for example 10, 20 , 30
- ch1 – Chart Label
- Labels separated by Vertical Lines (pipes)
- chd – Chart Dimensions (Maximum – 1000×300)
Make sure you take a look at Google’s documentation, it will show you how to do some more complex stuff.
