This visualization displays horizontal bar charts showing the relationship between patient age and insulin levels, with the title "Diabeties level vs Age." The bars are sorted by age in descending order, with the x-axis representing age values (0–60) and the y-axis representing individual patient IDs based on their insulin measurements. The visualization uses D3 v6 APIs including `scaleLinear` for the age axis, `scaleBand` for the categorical insulin values, and SVG rendering. Data comes from a CSV file loaded via `d3.csv`, featuring diabetes patient records with insulin, glucose, and other health metrics.
