{"version":"1.0","type":"rich","title":"Untitled","description":"This bar chart displays the number of students for various grades and locations, with bars colored blue and axes labeled \"Grades\" and \"Num_students.\" The visualization uses D3.js v6 to create an SVG rendering, employing `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the numeric y-axis. Data is hardcoded in an array of objects, while axes are generated with `d3.axisLeft` and `d3.axisBottom`. The chart includes a pink background rectangle and console logs for debugging scale behavior.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9337009c15f348909594e94b7686b406?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
