The ERP TIMEBAR displays stacked bar segments for event-related potential data across multiple series, with each colored group representing a factor level (Min, All, Max) over a shared time axis. The visualization animates bar growth using D3 v5 transitions, delaying each segment’s expansion to reveal the progression of values. It loads a CSV via `d3.csv` and `autoType`, applying `d3.stack()` and `d3.scaleBand`/`scaleLinear` scales, while `svg` rects are colored through a custom ordinal scale and rendered as SVG with timed `.attrTween`-like transitions.
