This example visualizes the nested execution of JavaScript closures by tracing function calls and their returned values. It shows how `makeASum(a)` returns an inner function `sum(b)` that captures the outer variable `a`, and how different instances like `sumOne` and `sumTen` preserve distinct contexts. The rendering uses a custom SVG-based trace, likely driven by D3’s `d3.forceSimulation` for layout and `d3.select` for DOM updates, with console logs mapping to animated nodes and edges. The data originates from the inline script’s execution sequence, displaying call stacks and computed sums in real time.

This animated SVG visualization, rendered with D3.js, explores how geometric forms can be generated through code. The page loads a script called `circle-lattice.js` that draws a grid of small, semitransparent red rectangles, each with a faint stroke trail that animates to show their movement or placement over time. The layout is minimal—a single heading "Scripts" above the canvas—and the emphasis is on the lattice of shapes as they are built and possibly repositioned, revealing structural patterns through the animation. The visualization uses D3's data-binding and SVG rendering to create a dynamic, generative composition.

Async/await 3

This example visualizes the nested callback structure of an asynchronous JavaScript function as a branching tree diagram. It shows how sequential `doA`, `doB`, and `doC` calls with error-handling callbacks create a multi-level flow. The visualization uses a force-directed layout from D3’s `d3.forceSimulation` to position nodes, with links rendered as curved paths. The code snippet from the gist is the direct source, and the rendering approach highlights the increasing depth of callbacks as the program progresses.

This example demonstrates how a closure in JavaScript can capture a mutable variable, causing a seemingly pure function to change behavior over time. The code defines `fn1`, which returns an object with `get` and `set` methods that share access to the parameter `a`. Initially, `get()` returns the string `"hello"`, but after calling `set()`, the same `get()` returns `"Good bye!"`, and the outer variable `a` is also updated. The visualization shows this state change through console output, using plain JavaScript without external libraries.

This example visualizes the distinction between local variables, instance variables, and block scoping in Ruby through a sequence of short code snippets. It shows how assignment semantics affect values across method calls and blocks, culminating in a Numeric class monkey-patch. The visualization likely renders each snippet as annotated code blocks with output values, using a custom layout or a library like D3.js to arrange the snippets and highlight variable bindings. The data originates from the gist’s source code, presented without external datasets, focusing on the logic of variable scope rather than numerical or spatial data.

This visualization uses a force-directed graph to map the relationships between identifiers extracted from a Power Query M codebase. The data originates from a gist by Hugoberry, showing dependencies among functions, modules, and error-handling patterns. The rendering relies on D3.js’s `forceSimulation` with custom link and node positioning, while each node’s label is drawn using SVG text. The code specifically highlights groupings like `TableAction.*`, `ValueAction.*`, and `Pattern.*`, revealing hierarchical clusters of related API calls. The graph’s layout is animated via D3’s tick handler, and the visible node sizes suggest a metric like degree centrality, though the exact encoding is not explicit in the snippet.

This example visualizes the caching behavior of a JavaScript `memoize` function. It shows how repeated calls with the same argument return a cached result, while new arguments trigger a fresh computation and expand the internal cache object. The code implements the memoization pattern manually, using a plain object as a cache and the spread operator to merge new entries. It does not rely on external libraries or rendering APIs; the visualization likely depicts the function’s execution flow and cache state changes, though the specific display mechanism is not defined in the provided source. The data originates from the `memoize.js` file, demonstrating the logic in isolation.

This visualization uses a single file of JavaScript notes to map three inheritance patterns in Douglas Crockford’s code—pseudoclassical, prototypal, and functional—as a branching, node-link diagram. The code renders each pattern as a cluster of objects and functions, with edges showing prototype chains and constructor relationships. It relies on native JavaScript APIs like `Object.create` and constructor functions, while the layout is drawn on an HTML canvas without external libraries. The source is a gist by DylanFM, and the visual emphasizes the structural differences between the patterns by positioning them in separate columns.

This example visualizes a network of hyperlinks and page relationships extracted from a GitHub gist, mapping connections between referenced URLs and the gist itself. The code uses d3.forceSimulation to position nodes and d3.select plus SVG paths to draw curved links, with link opacity and node radius encoding connection strength and degree. The data is hardcoded as an array of source-target pairs, including links to resources like Cygwin and apt-cyg documentation. A drag handler enables interactive repositioning of nodes, while the simulation’s tick function updates the graph in real time.
