I’ve released the software to generate a mental model diagram. You can feed your spreadsheet to it and a mental model diagram (the top half of an opportunity map) will appear on the page.
The software expects your data to be in a certain format. It looks for a spreadsheet where the first three columns represent the labels that make up the mental spaces, towers, and boxes of the mental model diagram.
In many people’s spreadsheets, the boxes are the summaries you’ve written to clarify what the participant was trying to convey.
You can also add a column if your data set is large, collecting several summaries into one box.
The rows can appear with spaces where you like them.
I have tested it with Excel spreadsheets, but not with other types of spreadsheet.

You can then download that diagram as an SVG file. (My developer and I ran into a bit of an issue downloading a PDF due to the long horizontal nature of the image, and the existing apps would break it up into printable pages.) People who tested this file format were able to load it easily into Illustrator.
To print a PDF, you will need to load the SVG file into appropriate software, e.g. Illustrator. Use similar software to add items below the towers. Download this example spreadsheet to try out. (PDF plug-in for browser coming in 2018.)
I set up a GoFundMe page for you to chip in to offset the cost of building this software. I don’t have a corporation or association backing me, so the money came from my own personal funds.
