1 · Federation Composition
Each dot represents ~14 surgeons. 400 dots = 5,444 members across 30 countries. Four color approaches compared.
A · Regional Grouping
Countries grouped by region share a color family (blues = Nordic, greens = DACH/Benelux, reds = Mediterranean, etc.)
B · Kelly's Maximum Contrast
Scientifically chosen colors for maximum perceptual distance between all pairs
C · Color + Pattern
10 base colors combined with patterns (solid, stripes, dots, ring) = 30 unique combinations
D · Hover Highlight
Original colors — hover over a dot to highlight all dots of that country (others dim)
2 · European Membership Bubble Map
Circle size proportional to number of members per country.
3 · Dot Density – Every Surgeon Counts
Each dot represents 10 surgeons. Colours grouped by country.
4 · Building the Federation
The top countries drive the numbers — but every society completes the whole.
5 · Hand Surgeons per Million Inhabitants
Normalized by population — a different perspective on hand surgery coverage.
6 · Color + Pattern — Dark
10 basiskleuren gecombineerd met patronen (solid, strepen, dots, ring) — zwarte achtergrond.
