This example demonstrates how JavaScript modules and dependencies are handled within an HTML page, highlighting the contrast between traditional script tags and ES6 module imports. It shows the console output of a string concatenated from variables exported across separate files, including `GetRekt.js` and `lmfao.js`, using named exports. The code uses ES6 `import` and `export` statements, which are bundled by Vizhub’s internal Rollup process when the file is named `index.js`. It visualizes the concept of topological sorting for script dependencies, though the actual rendering is limited to a plain HTML text display.

Notes:-

Problem with using <src = 'script.js> is when you have multiple scripts. you would have to organize them in such a way that the dependencies, if any are satisfied(manually keep track of which script depends on another script). For example, if in {script.js,script1.js,script2.js} consider script.js where you want to refer to a global variable in script2.js, you want the order to be {script2.js,script.js,script1.js}. The algorithm which does this ordering is called "topological sorting".
ES6 Modules : In Vizhub platform, when you rename the js file to index.js, a bundle.js is created(only in vizhub) by means of "rollup" internally(within vizhub). A bundle is a file that combines many modules together.
D3 only uses named exports
can use a CDN to import d3

JS in HTML

This example demonstrates how JavaScript modules can be seamlessly integrated into an HTML page using D3 v6. The page displays the text "Hello HTML" in large type, while the accompanying JavaScript logs greetings and exports to the browser console. It uses D3’s `select` import and modular exports from custom `something.js` and `thing.js` files, showcasing ES module syntax and dependency chaining. The rendering approach is simple static HTML with a CDN-hosted D3 script.

js in html

This example demonstrates a minimal HTML page that imports and logs a JavaScript module. It uses ES6 module syntax with `import` and `export` to load a constant value from a separate file. The page displays the text "Hello HTML!" in a large, centered message using inline CSS styling. The code shows how to structure a basic project with separate JavaScript files and the browser's module support.

JS in HTML

This example demonstrates how JavaScript can be imported and executed within an HTML document, with D3.js loaded via a CDN. The HTML file includes an empty body and a stylesheet, while the JavaScript imports `select` from D3 and logs it to the console, alongside a separate `script.js` that logs 'Hello'. A custom module `something.js` exports a string, showing ES module imports in action. The example highlights module structure and console output rather than visual rendering, using `d3.select` implicitly for demonstration.

JS in HTML

This example shows how to embed JavaScript directly in an HTML page alongside D3.js. It displays a large "Hello HTML!" message styled with CSS, while the bundled script.js and index.js modules log output to the console. The code imports named exports from something.js and other.js using ES module syntax, and loads D3 v7 from a CDN via a script tag. No data visualization is present; it demonstrates basic file structure and module wiring for a D3 starter project.

JS in HTML

This example demonstrates the integration of JavaScript within an HTML page, displaying the static text “Hello HTML!” styled with CSS. The code imports `something` from `./something.js`, which itself combines a string with the export from `./beautiful.js`, logging the concatenated result to the console. It also references the global `d3` object, though the D3 library is not loaded in the page due to the commented-out script tag. The example illustrates module-based code organization and console output without any interactive visualization.

JS in HTML

This example demonstrates how JavaScript code can be integrated directly into an HTML page using D3 v7. It defines three modules—`index.js`, `something.js`, and `thing.js`—that import from each other using ES6 syntax. The `index.html` file loads the D3 library from a CDN and displays a simple “Hello HTML” message styled with CSS. The JavaScript modules log text and the D3 `select` function to the console, showcasing modular code organization alongside standard HTML rendering.

JS outside HTML

A minimal HTML page demonstrates the separation of JavaScript logic from markup by importing a constant from an external module and logging it to the console. The example uses D3’s `select` function to highlight how modern JavaScript modules can be combined with D3 in a plain HTML environment. The page loads D3 v7 via a CDN script tag, while the application code imports from `./something.js` using the `import` statement, showcasing a React-free workflow that still leverages D3’s utilities.

JS in HTML

This example demonstrates a minimal, text-only visualization where the word "JS in HTML" is rendered at an extremely large font size (13em) and centered on the page. The visualization shows how D3 v6 can be imported and used alongside other JavaScript modules within a simple HTML document, with the code logging output to the browser's developer console. It uses D3's `d3.scaleLinear` and a named `select` import from the `d3` module, alongside custom modules (`something.js`, `thing.js`) that export strings. The page loads D3 from a CDN and executes both a main `script.js` and an automatically inserted `bundle.js`.
