{"version":"1.0","type":"rich","title":"22. D3 Bar Chart Rects","description":"A row of identical black rectangles is drawn on an SVG canvas, one for each value in a hardcoded array of twenty numbers. Using D3.js version 4.5.0, the code selects the SVG element, binds the dataset with `selectAll('rect')` and `.data()`, then appends rectangles via `.enter()`. All rectangles are initially positioned at x=0, y=0 with fixed dimensions of 20 pixels wide and 100 pixels tall, so the visualization currently shows no variation in height or position despite the differing data values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b99934f010ee419e89334d9687e95a14?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
