Being frustrated with existing options for creating ternary plots, I thought a better, quicker option should be available. After finding the d3-ternary library, I decided to hack together a small webpage for quickly making ternary plots for some of my courses. Afterwards I decided to develop it into a more user-friendly online tool available to anyone for free.
Thanks to Daven Quinn for developing the d3-ternary library. SVG download option based on SVG Crowbar. Explanation slides made with reveal.js and reveal-d3. The tables are HandsOnTables.

More Ternary Plotting Software
If your ternary plotting needs are not met by this site and need something more advanced, I'd suggest to checkout out this Python library, 'python-ternary', this R library: ggtern.
