This scatterplot visualizes the evolution of movie genres over time by plotting IMDb ratings against release years for a dataset of over 100 films. Each circle is color-coded by genre, with its position determined by the film’s release year and rating. The visualization is built using D3.js (v7) with scales from `d3.scaleLinear` and `d3.scaleOrdinal`. Interactive features include hover tooltips that appear after a delay and click-to-select highlighting.
