I've been using <a href="http://www.lucidchart.com/">http://www.lucidchart.com/</a> which runs just fine in Chromium and in Firefox. The downside is that you can't download an editable version using the Free version. I haven't bothered to upgrade to the paid version as I just work on my diagrams "in the cloud" and download .png files to host on our wiki.<div>

It's not nearly as "pretty" as Visio, but when designing stuff, less<br>
is often more.<br>
<br>
I'll observe that the MacOS product, OmniGraffle, uses GraphViz as its<br>
rendering tool. I think there's room for a tool that helps generate<br>
GraphViz files, graphically, but then uses the very-smart capabilities<br>
of GraphViz to arrange the objects on the page.<br>
<br>
The two things Dia has as serious deficiencies, doubtless compared to<br>
Visio, are:<br>
a) Inability to import from dynamic things (e.g. - like reading in SQL<br>
schemas to generate E/R diagrams, and such), and<br>
b) Absence of automatic layout.<br>
<br>
The "OmniGraffle model" of using GraphViz to manage layout could be an<br>
answer to that.<br>
