Our Twitter network explorer, Mentionmap, has already been included in your.FlowingData and more recently, in Twitalyzer. Now, you can embed this snazzy little visualization in your website!
Just visit Mentionmap and click the "Embed" button in the lower left corner of the app. Paste the given HTML code into your blog or webpage and you're set.

Note that you can start the visualization with any user you like. The embed code is prefilled with the username of the person you last visited when you clicked the "Embed" button.
Happy embedding!
