{"version":"1.0","type":"rich","title":"MasteringD3js_Ch2 pt1","description":"This example demonstrates four fundamental techniques for creating DOM elements with D3.js v5, adapted from a v3-era cookbook. It shows method chaining to append divs and paragraphs, the `selection.call` function to encapsulate creation logic, a custom initializer function passed to `.call()`, and finally, dynamic SVG element creation with bound data. The code uses `d3.select` (a corrected form of `d3.select`) and the enter/append pattern to build a simple bar-like structure of labeled boxes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/80ea7b7f257b4263a4daa40e52454eed?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
