Minimum html page.

This example demonstrates a nearly blank HTML page that loads a minimal document structure with a title, a linked stylesheet, and a script from a remote jQuery CDN. It shows the absolute foundation of a web page before any data or interactive visualization is added. The page references external `index.css` and `index.js` files, but the inline code provides no DOM elements, data loading, or chart logic. Its purpose is purely to establish the boilerplate shell—head, meta charset, and empty body—onto which any future visualization, such as a D3 force simulation or canvas drawing, could be attached. The code itself uses no specific data source or rendering API.

Huffman Encoding Ruby Implementation

This example visualizes the Huffman encoding algorithm as implemented in Ruby, using the source text "MISSISSIPPI_RIVER" as its input data. It shows how character frequencies are tallied and then assembled into a binary tree via a priority-queue-like process, with each node’s value representing a combined count. The code’s `Node` and `CountObject` classes build the tree, while the `collect_binary_values` method recursively assigns binary codes by traversing left (0) and right (1). The final output prints the character-to-code mapping and the encoded binary string, but does not use any external visualization libraries—the display is purely textual, relying on console output for both the tree construction steps and the resulting code table.

Simple Rack app as a Ruby file instead of config.ru.

This example shows a minimal Ruby web application built directly inside a single Ruby file, bypassing the conventional `config.ru` setup. It defines a `Hello` class with a `call` method that returns a static HTTP response—a status code of `'200'`, a `'Content-type'` header of `'text/html'`, and a simple HTML heading. The code uses the `rack` library’s `Rack::Handler::WEBrick.run` to launch the server, with the app logic exposed through the Rack interface. It also demonstrates how to start the server via the command line and test it with a GET request.

This example demonstrates how to read and write text and CSV files in Ruby, using the CSV library. It reads names from a text file into an array, prints the array, and then appends the word "likes" to each name before saving the result to another text file. The code also writes the original names to a CSV file. This is a file-processing utility rather than a data visualization, focusing on data manipulation and storage.

This example demonstrates a recursive Boggle word-finding algorithm that visualizes its search process by printing the game board to the console at each step. The code uses Ruby’s `Array#each_with_index` to scan the 4x4 letter grid, and recursively calls the `checker` method to trace valid adjacent letter paths for a given word. A `draw` function outputs the board state, marking previously visited cells with the string `"NO"` to show the algorithm’s backtracking. The visualization relies on terminal text output rather than graphical rendering, using only the `p` method for display.
