{"version":"1.0","type":"rich","title":"fm viz - students vs ratios","description":"This visualization shows student-to-teacher ratios across different students using two overlaid line charts, comparing two quantitative variables (d and e) for each student name. The data comes from a CSV file referenced from the UCI Machine Learning Repository. Built with Vega-Lite API and d3, the code uses vega-lite-api’s `markLine` and `encode` methods to map the categorical student names to the x-axis and the quantitative values to the y-axis, with the second line layered on top using `vl.layer` to combine both series. The visualization is rendered as an SVG, with custom styling for axes and labels defined in a configuration object.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3f80d422fe574ccfba9550076d6faf62?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
