Hi, I'm on Arch Linux and running this demo from GNOME Terminal. The Line chart font is not displaying correctly, is there a font I need to install?

Thank you for reaching out @hi019. This could be one of two things. It is either that the used font doesn't support unicode characters, or that the used terminal isn't compatible with termbox-go.

Can you try running the demo using tcell instead? The documentation for tcell is here:
https://github.com/mum4k/termdash/wiki/Tcell-API

An example of using tcell with termdash is here:
github.com/mum4k/termdash@2a7dafa3a8/termdashdemo/termdashdemo.go (L489-L490)

If this doesn't solve it, can you try it in a different terminal application and with a few different fonts to try to isolate the culprit?
