Simple chart example
Trying to import a VDX file generated by Lucidchart.com and it just opens as text file. Lucid is fast becoming SAAS charting standard.
I can confirm with Version: 184.108.40.206.alpha0+ (x64)

The document is not valid, because it does not specify namespace. But "VisioDocument" element name of the top element is hopefully specific enough, so I removed that extra check...
Btw, Visio 2010 refuses to open the document too. So if Lucid expects to become any standard, they should fix their export...
