{"version":"1.0","type":"rich","title":"append and remove elements in d3","description":"This example demonstrates how to select, filter, and style SVG circle elements using D3 v7. The page shows a row of five circles rendered inside an SVG container, with every other circle filled orange via `selectAll(\"circle\").filter()`. The code also includes commented-out demonstrations of `append()`, `remove()`, and `each()` for adding text, deleting elements, and applying conditional styling. Data is not loaded externally; instead, the circles are predefined in the HTML markup and manipulated directly through D3 selection methods.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/00096f768b784ccfb9128f49e05aa5ce?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
