{"version":"1.0","type":"rich","title":"My Line Chart with dropdown menu","description":"This interactive line chart visualizes daily PM10 emissions for various Italian municipalities during 2020. A dropdown menu allows users to switch between the different locations, and the line path animates smoothly to the new data when a selection is made. The chart is built using D3.js v6, which handles the SVG rendering, time-based x-axis scaling, linear y-axis scaling, and the dropdown's change event listener. The data is loaded from a CSV file fetched via `d3.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c16e30a54bd9418bad1a1c92fe659b09?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
