This example demonstrates a code snippet from a Merb global helper function that dynamically scales image dimensions while maintaining an 18-pixel vertical baseline. The function `scaled_image_tag` adjusts an image’s width to a maximum value and proportionally recalculates its height, rounding down to the nearest multiple of 18 to preserve grid alignment. It uses the Ruby `image_tag` helper from the Merb framework’s view layer, relying on standard hash options to pass width and height parameters. The code illustrates a practical rendering approach for responsive image handling in server-side templates, with no client-side visualization or data source involved.

This example demonstrates a Flickr photo management system built with Ruby on Merb, using the Flickr API to fetch, validate, and update photo metadata. It shows a batch workflow that first retrieves photos by category tags, then verifies their existence and tags on Flickr, and finally updates stored attributes like title, description, and image sizes. The code relies on Flickr’s `flickr_photo` objects and the Merb ORM for database persistence, with tasks chained via Rake. The visualization highlights the procedural data-sync logic, emphasizing error handling and association management between photos and categories.

This example uses a Ruby script to capture full-page screenshots of websites by automating a hidden WebView. It first loads a given URL, waits for the page to finish rendering, then saves the rendered content as a PNG file. The code leverages MacRuby’s WebKit framework, specifically `WebView` and `NSBitmapImageRep`, to render and capture the page. It supports optional width, height, delay, and output filename parameters, with a default width of 1024 pixels and a fallback to ruby-lang.org if no URL is provided.

This example shows a minimal Merb application that implements a contact form with server-side validation and email delivery. The visualization maps the request lifecycle, from the controller’s `contact` action handling POST data, through DataMapper model validation, to the `ContactMailer` dispatching a notification email. The code uses Merb’s `Merb::Mailer.config` for SMTP settings and `render_mail` for the mailer template. The gist includes controller, model, mailer, and environment configuration files, but does not include any data visualization—it is purely a code snippet collection, with no charts, graphs, or rendering APIs involved.

16:9 - Figma

This example demonstrates a Figma plugin that resizes a selected design element to fit a 16:9 aspect ratio. It calculates a multiplier based on the current width, then uses the `resize` method to set the dimensions to 16 times that multiplier and 9 times it, while also enabling `constrainProportions` to maintain the correct ratio. The code reads the selected frame's properties directly from the Figma API and modifies its dimensions accordingly.

This example visualizes the Mandelbrot set as a fixed ASCII-art plot in a terminal, using Ruby’s `Complex` class to iterate the function `z*z + c` fifty times per point. The code samples a 2D grid over the complex plane—x from -2.0 to 0.5 and y from 1.0 to -1.0—and prints an asterisk when the final magnitude is less than 2, otherwise a space. It shows a symmetric, high-level fractal silhouette rendered entirely with text characters, with no graphical libraries involved. The rendering approach relies on nested `step` loops and `Array.new(50,a).inject` to perform the iteration, producing the classic bulb-and-spiral structure directly in the console output.

This example demonstrates a command-line tool for capturing full-page screenshots of websites using MacRuby and WebKit. It shows a configurable web capture system that loads a URL, optionally resizes the viewport, waits for a specified delay, and saves the rendered page as a PNG. The code relies on the WebKit framework’s WebView and frame load delegation, alongside NSBitmapImageRep to rasterize the view’s content. Users specify options like width, height, output filename, and delay via Ruby’s OptionParser.

This example visualizes a short Apache configuration snippet from a gist, showing how a developer integrates Phusion Passenger with Ruby version management. The code demonstrates the use of `LoadModule` and `PassengerRuby` directives to switch between system Ruby and RVM-managed Ruby 1.8.6, with the data source being the gist’s raw text file. The visualization likely uses a text-based rendering approach, such as a syntax-highlighted code block, rather than a charting library, since the content is purely textual. No graphical libraries like `d3` or Three.js are employed; instead, the focus is on presenting the configuration lines as-is.

The issue & showcase

This example demonstrates how MooTools’ getComputedSize() method mishandles non-integer pixel dimensions, causing layout elements to overflow or disappear when a user zooms the browser. Three test cases show progressively larger compensation gaps between two floating divs, revealing accumulated rounding errors from internal toInt() calls. The page renders HTML divs and reports measured values in a live JavaScript report, directly comparing pixel-perfect layouts against zoom-level artifacts. It uses MooTools Core 1.4.4 and standard DOM APIs for size computation and display.
