This visualization presents survey responses about how much users would pay monthly for a music streaming subscription, displayed as a bubble chart overlaid on a y-axis of willingness to pay in euros. The React app loads CSV data and uses D3’s `forceSimulation`, `forceX`, `forceY`, and `forceCollide` to position bubbles in rows by amount, with circle sizes scaled to fit the viewport. Users can submit their own amount, which adds a bubble and enables clicking or hovering any bubble to reveal the respondent’s reasoning in an info panel.
