This bar chart visualizes Netflix stock closing prices over time, fetched from a CSV file and rendered as individual date-labeled bars. The code uses React hooks (`useEffect`, `useRef`) to manage the chart lifecycle and D3 v6 APIs including `d3.csvParse`, `d3.scaleBand`, `d3.scaleLinear`, and `d3.axisBottom`/`d3.axisLeft`. Bars are drawn as SVG `rect` elements with a steelblue fill, with dates rotated on the x-axis for readability. The chart dynamically fetches and parses the data before computing scales and rendering.
