This example demonstrates interactive multi-series time-series data visualization, showing temperature trends for New York, San Francisco, and Austin. Users can hover to highlight a specific line, click to toggle its visibility, and zoom along the x-axis using d3.zoom with rescaleX. Rendering uses SVG with d3.line and curveBasis, while the data loads from a TSV file parsed via d3.tsv and d3.timeParse. Styling applies CSS stroke properties, and the React framework supports the interaction handling.
