This bubble chart visualizes healthcare facility data, plotting the number of beds on the x-axis against average rating on the y-axis, with bubble size representing the number of doctors. Each point uses the `d3.scaleSqrt` function to map doctor counts to circle radii, creating a clear proportional comparison. The chart renders with SVG circles and D3.js axes, displaying a title and axis labels. It reads the data from a CSV file and updates the visualization asynchronously. The tooltip and hover effects provide interactivity, highlighting individual data points on demand.
