This scatter plot visualizes the relationship between BMI and heart disease status, using data loaded from a CSV file hosted on GitHub. The x-axis maps BMI values, while the y-axis encodes heart disease presence as a binary 0 or 1, with semi-transparent blue circles showing individual data points. Built with React and D3 v6, the code uses `d3.csv`, `scaleLinear`, `axisLeft`, and `axisBottom` to render the SVG chart across the full browser window, with custom margins and axis labels.
