This scatterplot visualizes fine-management event sequences over time. Each circle shows an event, positioned by its timestamp on the x-axis and its case identifier on the y-axis, while color encodes the activity type. The visualization uses D3 v5 to parse the CSV data, map timestamps with `scaleTime`, and ordinal categories with `scaleBand` and `scaleOrdinal`. Axis ticks are formatted with `timeFormat` and rendered as SVG elements within a defined margin.
