This bubble chart visualizes the distribution of movie ratings across six genres, using bubble size to represent the proportion of films within each rating category—from below 5.0 to above 8.5. Six genres are plotted along the y-axis while five rating categories form the x-axis, with larger circles indicating higher percentages. The visualization uses d3.csv to load the data and d3.scaleSqrt for bubble sizing, while d3.axisBottom and d3.axisLeft construct the axes. Interactive tooltips appear on hover, displaying the genre and its exact percentage for the “below 5.0” category, implemented through D3 event listeners.
