Q: Is the code behind this tool open source?

A: Yes. The repository for the SankeyMATIC code is at github.com/nowthis/sankeymatic.

Also, as mentioned at the bottom of every page, SankeyMATIC depends on the open source tool D3.js.

Q: How do I request a feature/report a bug?

A: Contact me on Mastodon at @SankeyMATIC@vis.social, or send email to 'sbogart' at this domain.

Q: Does SankeyMATIC send a copy of my data anywhere?

A: No. All processing of your data is done locally inside your web browser with JavaScript (including the generation of the PNG or SVG output), so no one sees your data or diagram until you publish it.
