{"version":"1.0","type":"rich","title":"SVG Fundamental","description":"This visualization shows the relationship between registration time and validity time for sequential data versions, displayed as stacked colored rectangles on an SVG canvas. Each version is represented by a distinct color (bisque, peach, coral, and orange), with rectangles positioned to indicate when each version was registered along the x-axis and its validity period along the y-axis. The chart includes labeled axes for both time dimensions, a legend explaining the color-to-version mapping, and axis markers indicating \"now\" on both timelines. The implementation uses raw SVG elements—including `rect`, `line`, and `text`—styled with inline CSS classes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/257bea271e884c30a5ac9ba4d78e4c02?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
