{"version":"1.0","type":"rich","title":"using dropdownlist","description":"This example shows average student attendance for university modules as an animated bar chart, with hover interactions that highlight bars and display their precise values. The chart loads data from a CSV file and renders it as SVG using D3 v4. It uses `d3.scaleBand` and `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and transitions with `ease(d3.easeLinear)` to animate bar growth on load. Mouseover and mouseout handlers modify bar dimensions, add a temporary text label, and apply CSS classes for styling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6451ab8fe3dd44fcb9e49f08eba2dbf0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
