This scatter plot compares gene expression levels across samples, plotting Gene X expression on the horizontal axis and Gene Y expression on the vertical axis to reveal potential correlations between the two variables. Each circle represents a sample, with hover interactions highlighting individual points in orange. The visualization loads CSV data via d3.csv, uses d3.scaleLinear for both axes, and renders circles, axes, and labels as SVG elements using D3 v7. A summary line displays the total sample count.
