Reporting is a major activity across all businesses. However, it is the visual impact of a report which makes it more interesting and readable to the user. Any presentation or report must contain information which is easily understood by any user at a glance. An image or a chart offer the best visual impact tolls in your report. Google has introduced an easy way of plotting graphs. They provide an api which provides you a chart or an image map with hotspot.
Google api is defined as
https://chart.googleapis.com/chart?cht=<chart_type>&chd=<chart_data>&chs=<chart_size>&...additional_parameters
All URLs start with https://chart.googleapis.com/chart? followed by the parameters that specify chart data and appearance. Parameters are name=value pairs, separated by an ampersand character (&), and parameters can be in any order, after the?. All charts require, at minimu, the following parameters: cht (chart type), chd (data), and chs (chart size).
Here is simple example of a Google api. For instance, if I pass the variables as
https://chart.googleapis.com/chart?cht=p3&chs=250x100&chd=t:60,40&chl=Hello|World
You can find the live code as well:
