{"version":"1.0","type":"rich","title":"Exploring survey data interactively - new join() version","description":"This interactive bar chart explores survey data, allowing users to select different variables for both the x and y axes via dropdown menus. It visualizes average values like height, stress, and family size, grouped by categorical preferences. The visualization uses D3 v5’s `join()` method to handle enter, update, and exit selections, dynamically updating scales, axes, and bar positions. Data from a JSON file is cleaned and nested using `d3.nest()` with rollups.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c635efa650a3433f830c7fb656d9c138?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
