I was wondering what the state of data about writable file formats per software application is in Wikidata. Here is a visualization of the data as of today:

What I learned from this visualization is that we need to enter more data about what writable file formats are supported by various software applications. Please let me know if you are aware of sources that list information about writable file formats that could be scraped to supply additional statements for Wikidata!

Feel free to try this query yourself here. I look forward to re-running this query periodically to see how the process of making this data more complete unfolds.
