{"version":"1.0","type":"rich","title":"d3 troubleshooting","description":"This example demonstrates how to troubleshoot common D3.js syntax and API patterns through annotated code snippets. It first highlights a JavaScript comma-versus-semicolon variable declaration error, then explains how D3’s axis functions generate tick marks and lines automatically. The final section walks through the core select–data–enter–append workflow, showing how empty selections bind data arrays and create new SVG `rect` elements. The code uses D3’s `d3.select`, `d3.selectAll`, and `.enter()` methods without external data sources.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-9f01c37241b4109ed6378007f42edeb9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
