A scatter plot displays the IMDB top 250 movies' ratings against their runtimes, with each point colored by its simplified genre. A dropdown filter allows viewing movies from a specific decade. The visualization uses D3 version 7 to project the data, with scales created via `scaleLinear`, a color mapping via `scaleOrdinal` and `schemeTableau10`, and axes rendered through `axisBottom` and `axisLeft`. The code processes movie data from a CSV file, including a custom genre preprocessing step, before rendering circles with hover tooltips that display the film's title, director, and release year.
