{"version":"1.0","type":"rich","title":"Line Chart","description":"This line chart visualizes GDP growth for top countries across 2017–2018, using a time-scaled x-axis and linear y-axis. The SVG rendering relies on D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` to draw the path. Data is loaded from a CSV via `d3.csv`, with axis labels styled through CSS. The chart includes grid lines and a single red trend line, with the y-axis tick format simplified using a custom formatting function.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/af7713d3fc074dc5adf0b7395c29fee6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
