{"version":"1.0","type":"rich","title":"d3 Updating Bar Chart With Dropdown","description":"A bar chart displays the number of students per university module, with a dropdown menu to select a specific course. Selecting a new module triggers an animated transition that updates the bar heights and y-axis domain. The visualization is built with d3.v3, using SVG rectangles and the `transition` method for smooth updates, while the dropdown change event calls the update function. Data is loaded from a CSV file containing module codes and student counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4aa87b702608489987fac4caa65a9442?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
