{"version":"1.0","type":"rich","title":"ACT6_TASK4.2","description":"This visualization displays movie runtime trends over time, with each bubble representing a film positioned by its release year and runtime in minutes, while the bubble size encodes its rating and the color indicates its simplified genre. The chart uses D3.js v7's `scaleLinear`, `scaleOrdinal`, and `schemeSet2` to map the data, and includes interactive legend items that highlight bubbles of a selected genre on click or hover. Data is loaded from a CSV file and preprocessed in React, with runtime strings converted to minutes and genres consolidated to the top seven categories.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f0a2a302e79a41678cc250dbec195ef3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
