Every state sits at the crossing of two numbers: how it voted (its two-party Democratic share of the 2024 presidential vote, running left to right) and how it is represented (the Democratic share of its United States House seats, running bottom to top).
The diagonal is the fair line, where a delegation matches the vote exactly. No state lands on it. The distance a dot floats above or below the diagonal is the bend: how far a state's delegation has been pulled from how the state actually votes. Larger dots hold more seats.
One caution worth keeping in mind: a state with only a handful of seats simply cannot divide them in fine proportion, so a small state far off the line may just be coarse arithmetic. And this compares a presidential lean to House seats, not the House popular vote. The genuinely notable distortions are the big delegations sitting far from the diagonal.
