I have been working on making a documentation page for some network. We needed some inline Visio diagram display so that regular end user could be able to see the diagram without generating (non up to date image export).

Download the file visio.zip(4Kb) and unpack it into lib/plugins folder or use the plugin manager. Download the (Free) Microsoft Visio Viewer 2003 and copy the .exe file to your server, then configure the plugin to have the correct path to offer the Visio viewer download to the end users.

Visio 2003 Viewer can be found under downloaded at Microsoft.

I borrowed some code from the video plugin.

{{my_visio_file.vsd[,width,height]|Alternate text}}

The plugin will generate the needed embedded object to view the visio file with Internet Explorer and Microsoft Visio Viewer 2003. (Ok, could be better, but quick and dirty solution).

There are some new configuration settings to set the default url for downloading the Microsoft Visio Viewer 2003 and default height and width.

I've installed the PlugIn on my Wiki. But if I have an vsd file - where I have to put it? (in german:Ich habe das PlugIn installiert in meinem Wiki. Doch muss mich ich die *.vsd Datei speichern, damit sie an gezeigt wird?)

It doesn't seem to work on Firefox…
