This example presents a basic line chart displaying a time series from a two-column CSV dataset. A single steelblue line traces the relationship between date and value over time. The chart is built using the D3.js library (v6), which handles CSV loading, date parsing, and the construction of a time-scaled X axis and linear Y axis. The line path is generated via `d3.line()` and rendered as an SVG element within a fixed 500x500 canvas.
