Add JSON-based plots to posts and pages using the plotly.js API

GNUPlot plugin allows you to draw charts inside your wordpress 
posts. The plugin will search the post for tags [gplot] and 
[/gplot]. Any thing in between will be used as a GNUPlot script, and 
resulting image will be placed in place of your tags.
The plugin communicates with a special version of GNUPlot hosted at 
clker.com, which means that you don’t need to have GNUPlot on your 
system.
Not all the GNUPlot commands are allowed. All commands that will 
result in execution, shell, reading or writing from the server are 
disabled in the hosted version. The size of the chart is limited as 
well to avoid excessive CPU usage.
After your plot is generated, the plugin caches the result locally in 
wp-content/cache. You will need to make sure that this directory 
exists and is writeable by your webserver.
