TheGoogle Chart API is a non-interactiveWeb service (nowdeprecated) that createsgraphicalcharts from user-supplied data. Google servers create aPNG image of a chart from data and formatting parameters specified by a user'sHTTP request. The service supports a wide variety of chart information and formatting. Users may conveniently embed these charts in aWeb page by using a simpleimage tag.
Originally theAPI was Google's internal tool to support rapid embedding of charts withinGoogle's own applications (likeGoogle Finance for example). Google figured it would be a useful tool to open up to web developers. It officially launched on December 6, 2007.
Currently, line, bar, pie, andradar charts, as well asVenn diagrams,scatter plots,sparklines,maps, google-o-meters, andQR codes are supported.
Google deprecated the API in 2012[1][2] with guaranteed availability until April 2015. On March 18, 2019 Google turned off the API.[3] Google recommends the successor serviceGoogle Charts.[4]
The following URL creates the pie chart below:

&chdl=Asleep|Awake
&chd=t:1,11,1,11,1,11,1,11,1,11,1,11

Instead of creating the URL request manually, there are many open source libraries available for most programming languages.
