Hello VizHub
Hello VizHub demonstrates VizHub’s ability to run an ES6 module and render styled text using D3 v5. The code sets a greeting string via `select('#message').text(message)`, sourced from an exported constant in `myMessage.js`. Styling uses CSS with the Ubuntu font and a dark background. It showcases basic D3 selection, text manipulation, and modular JavaScript imports within the VizHub environment.
