Datoviz - Installation guide for Windows: Running Datoviz test
python -c "import datoviz; datoviz.demo()"
gets following error:

13:40:01.092 W C:\Users\cross\Documents\GitHub\datoviz\src\ticks.h:0695: automatic tick positioning on interval [-inf, 3.696173] failed (found [-inf-3.696173] with step inf

I also run into the error on Windows 10 when running datoviz.exe demo. This particular issue is with demo_scatter() function.

I see the same error when I compile the standalone_scene.c, which is very similar but about 50% of the time instead of 100% of the time.

The difference between these looks to be the number of markers being rendered. So I changed the value of N to 50, and I don't see any of the same errors, in both the demo executable or the standalone code.

The demo still crashes, but it does render the canvas properly before it crashes. Looks to be an issue when it tries to save the screenshot, but that's an unrelated issue.

Thanks for the bug reports. Windows remains a pretty much untested platform, but I'll work on improving this in the coming months.
