{"version":"1.0","type":"rich","title":"neues barchart v3","description":"This interactive bar chart displays the absolute frequencies of categorical values from a dataset of student grades and degree programs. Users can switch the category displayed on the x-axis via a dropdown menu, which triggers a re-render of the chart. Built with D3 v5 and React, the visualization uses `d3.nest()` for aggregation, `d3.scaleBand()` and `d3.scaleLinear` for axes, and animated transitions on hover to highlight bars and show value differences. Tooltips appear on mouseover, while axis labels and titles update dynamically.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f120d2e45dd3459ab21d384f3a14c7a4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
