Built with ECharts 5.3.1, the visualization loads data from a CSV file containing synthetic student records, parses it with a custom parser, and calculates mean grades per group. The line chart reveals how academic performance varies across different study-hour ranges, with the data filtered to include only records with valid gaming, study, and grade values.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/beb2d4c2366543cbb6467773d53cda90?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
