{"version":"1.0","type":"rich","title":"Step 3 Line Chart","description":"This line chart visualizes sales figures from 2011 to 2021, with the x-axis mapping years as dates and the y-axis representing sales values. The chart uses D3 v5's `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, and `line` generator to render an SVG path, with data loaded via `d3.csv` from a GitHub gist. Gridlines are created through axis tick sizing, and a red stroke highlights the trend line.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/302c045b4b4a4ef78283c9e4ac51fe7f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
