Creating charts has never been easier. Heck, you’d almost call it fun.
This plugin allows the user to create and insert a Google Chart in just a few short clicks. Check out the <a href="http://brockangelo.com/wordpress/plugins/google-chart-generator/" rel="nofollow ugc">working online demo</a> to see for yourself.

With <a href="https://github.com/pixelgrade/pixcodes" rel="nofollow ugc">PixCodes</a> you can have a shortcode insert interface.
The awesome part is that you can filter any shortcode parameters or overwrite any shortcode template with your theme.
Note: this plugin does not add any style to the output of shortcodes.
We believe that shortcodes functionality should be offered by a plugin and the style should be provided by themes.
Here is a <a href="http://github.com/pixelgrade/pixcodes/blob/master/README.md" rel="nofollow ugc">detailed documentation</a> about how you can configure some plugin settings and output.

PixCodes

PixCodes offers you a nice interface to add shortcodes into editor.
