{"version":"1.0","type":"rich","title":"multi line chart- d3","description":"This multi-line chart visualizes changes in six continental populations—Africa, Asia, Europe, North America, Oceania, and South America—over time using data loaded from a remote CSV file via `d3.text`. The code renders six distinct colored lines using `d3.line` paths within an SVG, with each region assigned a unique stroke color. The chart uses `d3.scaleBand` for x-axis months and `d3.scaleLinear` for y-axis values, which is fixed between 1,000 and 3,600,000. Interactive circular markers, created with SVG `circle` elements, display tooltips on mouseover via `d3.select` and event listeners, showing the specific data values for each month. The visualization is built with React, utilizes D3.js version 7, and is rendered entirely as vector graphics.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3a1f5463de674fb1b7b119c5748e19a0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
