{"version":"1.0","type":"rich","title":"D3 Tutorial","description":"This tutorial demonstrates a simple line chart of yearly values from a CSV file, showing the trend of data points from 1970 to 2019. The visualization uses D3.js v6 to load the `data.csv` file and render an SVG chart. The code sets up a fixed-position chart container and relies on D3's selection and data-joining methods to plot the series. While the JavaScript implementation is incomplete, the example highlights D3’s fundamental workflow for binding external data to visual elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3765decc34a145d6ad26c381824edd01?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
