{"version":"1.0","type":"rich","title":"bubersson3 - express route","description":"This example demonstrates a minimal Express.js route handler that serves an HTML page with dynamic data. The code defines an HTTP GET endpoint for `/lect1.html`, where a local variable is conditionally assigned a value before passing it to a template renderer. The route uses Express’s `res.render()` method to populate the `lect1` view with the variable as `my_var`. The visualization shows how server-side logic can inject computed values into a template response, though the actual rendering framework (such as EJS or Pug) is not specified in the snippet.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-1324312?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
