I am trying to change the color of the bar graph that is beside the default blue. I am looking at the :color encoding but I am unsure how that works. Can someone give me an example code of how that works? I wanna use hexcodes.

This is currently not supported, I will add it the new release, for now you can do:
data = [
%{"a" => "A", "b" => 28},
%{"a" => "B", "b" => 55},
...
]
plot = Tucan.bar(data, "a", "b", color: [datum: "red"])
%VegaLite{
plot
| spec: update_in(plot.spec, ["mark"], fn opts -> Map.merge(opts, %{"color" => "#fa1243"}) end)
}
PS. Fix pushed, you can now use fill_color: your_hex_here in the bar chart. You need to add it as git dependency for now.

I was also wondering if you guys can also add the rounded edges option in the bar graph? I would love to see that because I know vegalite has that too
