Plugin for adding visual elements such as flowcharts

[riverstream]

Hi!

I'm looking for good suggestions on plugins to easily add shapes, flowchart and timelines - to my posts and pages. I'm looking for something that's easy to use, perhaps contains a few templates, integrates with the design, etc. I'm not looking for a generic chart plugin, but rather something to dynamically build visual elements (such as flowcharts).

All suggestions are welcome and apologizes if this is in the wrong forum.

Thanks!
