{"version":"1.0","type":"rich","title":"World population area chart","description":"This interactive area chart displays the duration and timing of 51 user traces, with each rectangle representing a single session’s start time along the x-axis and its length in minutes along the y-axis. Clicking a rectangle opens a popup showing trace number, start/end times, and duration. Built with D3 v5, the visualization uses `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and SVG elements, with background rectangles color-coding activity regions. Data is loaded from a local CSV file, and hover effects highlight individual traces.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4bb19867082c446dbb893da0e5f7f156?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
