{"version":"1.0","type":"rich","title":"A Line-Chart with D3.js","description":"The visualization displays yearly average rainfall and temperature in Germany from 1991 to 2015 as a dual-line chart, with red lines for temperature and blue lines for precipitation. It uses D3.js v5.7.0 with SVG rendering, leveraging `d3.nest()` to group raw CSV data by year and `d3.mean()` to compute annual averages. The chart implements linear scales, axis generators (`d3.axisBottom`, `d3.axisLeft`, `d3.axisRight`), and line generators to plot the two time series, with labeled axes for clarity.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b91166b728da41899d40ad7820031590?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
