{"version":"1.0","type":"rich","title":"Activity6_population","description":"This example visualizes population trends across multiple countries from 1950 to 2020 using a line chart built with D3 v5. The data is loaded from a CSV file containing yearly population figures for countries including China, India, and the United States. The visualization uses D3's `select` function to manipulate the DOM and render the chart. The code demonstrates ES6 module imports, including local modules like `myMessage.js`, and sets a greeting message using D3's text manipulation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0f18f711437d4cb882b324eb663be7e5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
