draw.ioimport
I've been trying to import a Visio .vsd file into the draw.io web application, without success. I've seen various online references to Visio import being supported, but no exact steps.
I've tried "File->Open From" and dragging and dropping the file into a blank diagram, but nothing appears to happen.
The marked answer is old and is no longer correct.
Click Arrange → Insert → Insert Image.
Yes, you can now use the draw.io Google Docs addon to directly embed a draw.io diagram within a Google Doc. This is the listing for the addon, but it's easier to open a Google Doc, select "add-ons", then "get add-ons" from the menu:
A panel of add-ons will then display. In the search box type "draw.io" and click "install" to add the draw.io plugin.

diagrams.net online supports the legacy .vsd format and the .vsdx format, which is the default format from the 2013 and 2016 versions of the tool.
The actual process of importing to either drag and drop the .vsd(x) file into a diagram, use "File->Import From", or "File->Open From".
