{"version":"1.0","type":"rich","title":"Fork of Margins_drb","description":"This example demonstrates how margins define the inner rectangle of a visualization, reserving space for axes and marks. The chart renders a neon green rectangular plotting area with a single green circle at coordinates (308, 390), positioned relative to the container’s client dimensions. Using D3.js (version 7.8.5), the code leverages selections and joins to create the SVG elements, computing inner width and height by subtracting fixed 50-pixel margins from the container size. A gray gradient background is applied via CSS, and the data itself is hardcoded as placeholder values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/edb3745b273c4a8bb9af43fc859ad928?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
