This scatter plot displays stock market data, with each point representing a stock's opening and closing prices. The visualization uses color to categorize stocks into three types: Tech, Finance, and Healthcare. The plot is rendered as an SVG using D3 v6, with data loaded from a CSV file hosted on GitHub. The code uses `d3.scaleLinear` for axes, `d3.axisLeft` and `d3.axisBottom` for axis rendering, and `d3.select` to append elements to the body.
