How It Started
This is the new and improved TernaryPlot.com! Initially I built this as a small tool for myself to quickly make many ternary plots and avoid having to work with janky Excel templates or dealing with Python or R. Later on, I built it into a user-friendly website, which will remain available at ternaryplot.netlify.app but will no longer receive updates.
As feature requests piled up and my webdev skills improved, the time for a complete rewrite was due. Well, here we are.
If you need custom, interactive ternary plots in the browser you can make them using d3-ternary (and JS ofcourse). Learn more about it in this introductory Observable notebook Introducing d3-ternary.
If you plan to use a ternary diagram from here in a scientific paper, that's great, go ahead! Please do mention www.TernaryPlot.com in the footnotes.
