Color by travel count: None, 1, 2, 7, 12, 18 is fine but a segment with 17 travels has the color indicated for 18. Maybe None, 1, 2, 3..7, 8..12, 13..18 etc?
Every value has a different color (up to 240 max travelers). I need to look into a gradient scale instead of the fixed boxes.
I just talked about the
legend. I'd like to see the actual range, e.g. 3..7 instead of the upper limit only because it could be the upper or lower limit.
If the actual limits are
None, 1, 2, 3..7, 8..12, 13..18 you could indicate
None, 1, 2, 3..7, 8..12, 13..18 in the legend
orNone, 1, 2, <= 7, <= 12, <= 18
orNone, 1, 2, < 8 , < 13, < 19
OTOH, you use a gradient scale now..... but still, I need to figure out that it is the upper limit. I think it is not intuitive
