{"version":"1.0","type":"rich","title":"Tree example","description":"This tree diagram visualizes the distribution of correct and incorrect responses across math problem conditions from an eye-tracking study by the WPI MAPPLE lab. The hierarchical layout shows branches for problems with and without brackets, further split by bracket position and response type. Built with D3 v7, it uses `d3.hierarchy` to process JSON data and `d3.tree` to compute node positions. Circles represent nodes, connected by blue lines, all rendered within an SVG canvas sized to the window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/99b26d5422c04a77a0ec6b6bd5bc892b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
