{"version":"1.0","type":"rich","title":"fresh block","description":"A single black polyline traces a line chart of twelve data points, mapping step numbers to values on a fixed SVG canvas. The line is drawn using `d3.line()` with linear scales (`d3.scaleLinear`) for both axes, and the path is rendered with `fill: none` and `stroke: black`. The code defines a secondary set of coordinates but never uses it, and the chart shows only the line without axes, labels, or interactive elements. Data is hardcoded in a JavaScript array.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-23562a8cb3fb1f4a98aacac89f4d31d4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
