{"version":"1.0","type":"rich","title":"Untitled","description":"This example shows the annual variation of a single numeric value from 1895 to 2019, plotted as a time series using D3.js v6. The visualization calculates an SVG line chart from a CSV file with two columns, mapping the year to the x-axis and the value to the y-axis. The code loads the data with `d3.csv`, appends an SVG canvas with a fixed width and height, and prepares to render the dataset, though the drawing logic is incomplete. The chart relies on D3’s data-joining methods to bind the parsed rows to visual elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fed168277f614ea5842a67691f5ac797?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
