This example displays stock price data for a vegetable-related dataset, plotting the Open, High, Low, and Close values over time from 2019. It uses a line chart with a brush-and-zoom interaction, allowing the user to select a time range and inspect price fluctuations across all four metrics. The visualization relies on D3.js APIs such as `d3.line`, `d3.brushX`, and `d3.zoom` to render the paths and manage the interactive focus and context panels. The data is loaded from a CSV file and rendered with SVG elements.
