Parcoords plot causes out of memory error or browser hang if data is all zeroes

[jonathonw]

Parallel coordinates plots cause browser out of memory errors (on Chrome) or browser hangs (on Firefox) if a dimension's values are all zeroes and the dimension's range is not specified or also set to [0, 0].

Minimal example: https://jsfiddle.net/JonathonW/p5rj2uv4/8/

This issue is not reproducible if the range is explicitly set (to something other than [0, 0]), or if the dimension's values are non-zero (even if they are the same-- value: [1, 1] does not cause the same problem).

@jonathonw thanks for the report.
This is a 1.49.0 regression as your example works with previous versions codepen.
The browser stops here:

plotly.js/src/plots/cartesian/axes.js

Line 1373 in 76f7652

for(var i = tickRound; i < 0; i++) v += '0';

possibly to avoid an infinite loop.
