This example shows a sequence explorer visualization where individual events are displayed as horizontal bands that do not connect from one step to the next, emphasizing discrete stages rather than continuous flow. The chart uses D3 v4 and the custom `sequence-explorer.v20.min.js` library, with data loaded from embedded CSV-like text blocks. It renders nodes as rectangles and paths with varying stroke widths based on frequency values, while the CSS rule `path.lsx1.ltx1 { stroke: none; }` hides all vertical segments, making only horizontal transitions visible. The code initializes the chart via `sequenceExplorer.chart().showNodeLabels(false)` and binds it to a `div` using `.call()`, with a sample dataset containing frequencies for drinks like beer and cider across three time steps.
