{"version":"1.0","type":"rich","title":"空教室查询","description":"This example is an interactive web tool for querying empty classrooms at a university. It displays a form where users select a semester, week range, campus, and building to filter available rooms. The interface uses chained dropdown menus that update via AJAX calls to server endpoints like `/kjscx/querykclistbyxnxq` and `/kjscx/queryJxlListBySjid`, populated with JSON data. Results are rendered as a table, with validation requiring a semester and week selection before submission.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/69cefecad03c4076934c4a4e134461c6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
