{"version":"1.0","type":"rich","title":"General Update Pattern - reusable: alphabet example v3","description":"This example demonstrates the general update pattern for data joins in D3 v5, showing how text elements enter, update, and exit as the underlying array changes. It renders animated SVG text using a reusable chart module with configurable width, height, and margins. The code uses `d3.selectAll().data()` with a key function, `transition()` for 750ms animations, and `merge()` to combine enter and update selections. Each state is color-coded: green for entering, steelblue for entering-and-updating, black for updating, and brown for exiting elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9fce1936cdd74dc4bc5fbf7643ca8df3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
