Description
Hello!
While browsing the plotly.js documentation to understand how to make ternary contour plots, I noticed an inconsistency.
Indeed, what is presented as an example for ternary contour plots seems to be a classical ternary plot with blocks colored.
Screenshot 1 : When on the page, it states ternary contour plots as the title, but the subtitle already indicates that it is probably not.

Screenshots 2 and 3 : what is shown as example (2) and what is shown as an ternary contour plot in the menu of Plotly.js scientific charts (3)
I think it's only an inconsistency, as plotly python allows to do that sort of graps, and - if I'm not mistaken - Plotly Python is powered by the same JS core. :)

Research direction
Start at the ternary contour plot documentation page and compare its title, subtitle, menu entry, and displayed example with the reported expectation. Confirm what Plotly.js supports, then update the documentation so the example and labeling accurately describe the plot shown or the intended ternary contour plot.
