{"version":"1.0","type":"rich","title":"line chart Ice_7","description":"This line chart shows the exam scores of ten students alongside their study hours, with each score point rendered as a distinct shape that changes by score range: triangles for scores under 60, diamonds for scores between 60 and 80, and crosses for scores above 80. The line itself uses a vertical gradient stroke, transitioning from green at lower scores to red at higher scores, with a dashed pattern. Built with D3 v7, the code employs `d3.scalePoint`, `d3.line`, `d3.axisBottom`, `d3.axisLeft`, and `d3.symbol` with triangle, diamond, and cross generators, all rendered as SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
