This bubble chart displays IMDB’s top 250 movies, plotting each film’s release year against its runtime in minutes, with bubble size encoding rating and color representing the seven most common genres. The visualization uses D3 scales, including `scaleLinear` and `scaleOrdinal` with `schemeSet2` for categorical coloring. React manages the data-loading lifecycle, while D3’s `select` and `join` methods handle SVG rendering and updates. The chart includes labeled axes with formatted ticks, a legend, and a title, all positioned within configured margins.
