Use Unicode Block Graphics U+2581-U+2588 for bar graphs
Is your feature request related to a problem? Please describe. The vertical resolution of the bar graphs is a character cell. It'd be 8x higher if using the block graphics between U+2581 and U+2588. Alternatively, horizontal and vertical resolutions can be doubled with 2x2 mosaics from U+2599 to U+259F. Optionally, depending on termina/font support, we could triple vertical resolution with the 2x3 mosaics introduced in Unicode 13
Describe the solution you'd like Graphs would have a higher resolution
As soon as I figure out how the bars are drawn. Is this in this codebase or is it something that comes from urwid?

Most of the parameters of urwid can be overridden, we do some of it in sturwid.
I guess this can be as well. @giltsuker is the expert on this honestly
From what I can tell and remember a bit, In bar_graph_vector.py, after we call the constructor of the native BarGraph class, I think you can override the native characters of the urwid base class. override:
- self.eighths with the array for the top of the columns
- self.char with the "base" char for the rest of the column
Note that they should be an array I think for the 2 types of colors we use. Probably some trial and error will be needed :)
Funny. You are not overriding the eights, but I saw the graph with full cells only... The eights should show.
