This bubble chart displays the relationship between the release year and runtime of the top 250 IMDB movies, with each bubble’s size representing its rating and its color indicating a simplified genre. The visualization reveals a general trend of increasing movie runtimes over time. It uses a React frontend with d3.v7’s `scaleLinear`, `scaleOrdinal`, and `axisBottom` to map data. Data is preprocessed from a CSV file, with runtimes parsed from strings like “2h 22m” into minutes. The genre legend allows interactive highlighting, filtering bubbles by genre on click or hover.
