Native support for PNG exports

[concimuscb]

For Windows users, you have to install GTK in order to be able to export charts to PNG.

Since this cannot be reflected in requirement files it adds a layer of complexity when onboarding new team members.

AFAIK nearly all other libraries support PNG exports natively (read, you simply pip install whateverplottinglibrary and PNG exports will work).

Are there any plans to support this in the future?

Hi, the GTK dependency is one of several reasons why we're planning to move away from CairoSVG for PNG/PDF exporting. We'll begin working on this after the holidays.

Hi @concimuscb , could you try v4.7.0?

PNG/PDF export was completely reworked and the CairoSVG dependency has been dropped. The new implementation is based on ImageMagick, which is bundled in the Lets-Plot binaries.
