Animated bubble chart tracks the changing acreage burned by wildfire causes across nine time periods. A slider selects each dataset, triggering a D3 force simulation that transitions circle positions and sizes to reflect the new values. Circles are colored using a chromatic scale and labeled by cause, with hover effects highlighting individual nodes via SVG styling. The visualization relies on d3.forceSimulation for layout and d3-transition animations to smoothly interpolate between states, rendering wildfire statistics as a comparative, interactive time series.
