This multi-series line chart visualizes Tesla stock price data from the `electric_production.tsv` file, displaying multiple time-series lines over a shared date axis. Using D3 v7 with SVG rendering, the visualization supports interactive zooming via `d3.zoom` and panning, with individual series toggleable through click and hover interactions that adjust line opacity and color emphasis. The chart applies basis curve smoothing for line rendering, and the color scheme uses `d3.schemeCategory10` to distinguish each series. Animated transitions are included when scaling the view.
