Description

Dear fellow developers and plot.ly users,

I would like to request a new feature: "symmetrical log" scale. Matplotlib has it:

http://matplotlib.org/examples/pylab_examples/symlog_demo.html

Also see: What is the difference between 'log' and 'symlog'? link

It would be great if plot.ly can adopt this scale. Thanks!

Research direction
Examine existing scale implementations in plotly.js, particularly the 'log' scale. Study matplotlib's symlog implementation and adapt it to plotly.js. Refer to the linked StackOverflow discussion and any comments in the issue for additional context. Implement a symmetrical log scale that transitions from linear near zero to logarithmic elsewhere.
