Bubble Testing
The visualization shows a bubble chart of characters from a movie, where each bubble represents a character and its size corresponds to the character's total word count. The complex-looking interface includes a toggle switch that lets users flip the data between categorized and combined states, changing both bubble colors and the simulation's force dynamics. Built with D3 v4, it uses `d3.forceSimulation`, `d3.forceX`, and `d3.forceCollide` to animate bubble positions, while the toggle triggers a transition that swaps between male/female color schemes and adjusts the force's strength. The data comes from a local CSV file, and rendering is done via SVG with animated transitions.
