{"version":"1.0","type":"rich","title":"Activity 6","description":"This example demonstrates how to combine D3.js with ES6 modules in a VizHub project. It imports the `select` function from D3 and a custom local module called `message.js` to display the text “Hello VizHub!” centered on the page. The code uses `d3.select` to target the `#message` div and sets its text content, with styling applied via an external CSS file. The example also includes a regular expression and a constant variable to illustrate additional JavaScript syntax, though these do not affect the visual output.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a0712f3e029c4375b7e79b327505ae65?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
