This chart shows the number of units purchased by each of ten sales representatives as horizontal bars labeled with the representative’s name. The visualization uses React components to render an SVG scene, with D3’s `scaleBand` and `scaleLinear` mapping the categorical and quantitative data to pixel positions. Axis ticks and grid lines are generated manually from D3’s `xScale.ticks()` and `yScale.domain()`, while the data is loaded from a CSV file via `d3.csv`. The example demonstrates integrating React’s state management with D3’s scaling and layout utilities for declarative SVG rendering.
