{"version":"1.0","type":"rich","title":"Let's make a bar chart!","description":"This example shows the cumulative number of events by year from 1949 to 2019, using a bar chart that grows in height as the running total increases. The visualization loads CSV data and renders it as SVG rectangles, using D3 v5 scales (`d3.scaleLinear`, `d3.scaleBand`) and axes (`d3.axisBottom`, `d3.axisLeft`). The bars are colored steelblue and positioned via the scale’s range band, with the chart drawn inside an `<svg>` element using a margin convention.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/773f9379259c4c3d94e89886e372ebc2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
