The German Bundestag as a room full of seats
Between the two sittings the AfD grew from 83 to 150 seats and the SPD fell from 206 to 120, in a parliament that shrank from 735 to 630 seats.

How to read it

Redrawn from the published figures. The recreation follows the original’s order and colours.
Why this chart
- It is a part-to-whole chart for a whole that is literally a room: anyone who has seen a parliament understands the shape before reading a word.
- Seats are discrete. One dot per seat keeps the unit honest, where a donut would turn 630 people into a continuous slice.
- The half-circle leaves a natural place for the question that matters most in a parliament, the majority threshold, as a single line.
What works
- Party colours readers already know, so the legend is barely needed
- A majority line turns the picture into an answer: who can govern?
- CDU/CSU placed next to the SPD, so the governing coalition reads as one block that crosses the line
- A table beside the chart gives exact numbers, so nobody has to count dots
- A switch between sittings invites the comparison the post is about
What to watch
- Blocks of similar size are hard to compare as dots: the Greens’ 85 and the Left’s 64 look alike. The table carries the precision.
- The chamber shrank from 735 to 630 seats, so comparing counts across the two tabs mixes a change in size with a change in support. Shares compare fairly.
- The order is not the chamber’s left-to-right seating. Parliament charts usually follow the political spectrum, so that neighbouring blocks are plausible partners.
- The 2026 tab shows the parliament elected in 2025 as it stands in 2026; party groups change during a term, so a seat chart is a snapshot of a date.
- Black dots for CDU/CSU nearly disappear on a dark background without an outline.
What we can learn
- 01Use a unit chart when the units are real: seats, people, votes.
- 02Draw the threshold that matters, a majority or a target, instead of leaving readers to compute it.
- 03Order the parts so the combination you want to discuss is contiguous.
- 04Compare wholes of different sizes as shares, not counts.
- 05Pair the picture with a table: the picture for the pattern, the table for the numbers.
The same data as a grouped bar chart
Bars compare each party’s change more precisely than dots, but the room, the majority and the question of who can govern all disappear.
