This visualization displays Ecuadorian holiday events as a bubble chart, with circles grouped by locale along the x-axis and sized by the total count of holiday records per locale. Each bubble is colored by the holiday type using a categorical color scale. The chart uses d3.csv to load the data, d3.rollup to aggregate counts, and d3.scaleBand, d3.scaleLinear, and d3.scaleSqrt for positioning and sizing. Interactive tooltips appear on mouseover, and a legend identifies the color encoding for holiday types.
