{"version":"1.0","type":"rich","title":"Document","description":"Two small SVG charts display time blocks as steel-blue bars against a 24-hour y-axis, with each chart representing a different dataset of start and end hour ranges. The code uses d3.v3’s `d3.svg.axis` and `d3.scale.linear` to map hours to vertical positions, calculating tick distance to size bar heights. Bars are appended as `rect` elements via `selectAll` and `enter()`, with opacity set to 0.5. Data are hardcoded arrays of objects, rendered side by side in Bootstrap grid columns.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-5bdec1c45e22b6d4e60fe450dad4af6b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
