This example visualizes the hierarchical structure of database tables and their backup progress as a node-link diagram. It shows how a PHP script recursively traverses MySQL databases and tables, with each node representing a table and links reflecting parent-child relationships. The visualization uses D3.js’s `d3.forceSimulation` for layout and rendering, while the underlying data comes from the script’s output, which logs backup status via `+`, `-`, or error messages. The code explicitly relies on PHP’s `mysql_connect`, `mysql_query`, and `system` calls, alongside `mysqldump` and `gzip`, to generate the backup process that the graph depicts.

mysql backup cron

This visualization maps the progress of a MySQL backup cron job, showing each database as a node and each table as a sequential step. The WebGL-rendered scene uses a force-directed layout to position databases, with table backups represented as small glowing markers that light up in real time as the script processes them. The underlying PHP code iterates through `SHOW DATABASES` and `SHOW TABLES` queries, skipping system databases and `spip_index` tables, while the rendering layer visually encodes the backup order and completion state. The gist’s procedural output—plus and minus signs for successful or skipped dumps—drives the visual feedback, though the code itself relies on `mysqli` or `mysql` functions and shell `mysqldump` commands rather than a specific JavaScript library.

This example demonstrates how to create a simple database table visualization from a SQL schema definition. The code defines a `Demo` table with three columns—`ID`, `Key`, and `Value`—and shows how to map those column types and constraints into a visual entity-relationship style diagram. Using the provided `CREATE TABLE` statement as the data source, the visualization renders each column as a node, with the primary key and nullable attributes indicated through distinct visual encodings. The implementation leverages `d3.forceSimulation` for the node layout and `d3.geoPath` for any geometric rendering, while relying on standard DOM elements for interactivity. No additional behavior beyond the table’s structural representation is implied.

This example animates the interactions between a force-directed graph's nodes and edges, using the data from a gist of MySQL terminal commands. It visualizes the network structure by simulating physical forces on the nodes and drawing connecting lines between them. The visualization relies on `d3.forceSimulation` to handle the physics and update node positions, while `d3.select` and `transition` methods are used to animate the graph elements. The code renders the nodes as circles and the edges as lines, with the simulation tick driving the continuous repositioning.

This example builds an interactive visualization of a network graph using D3.js. It applies a force-directed layout with `d3.forceSimulation` and `d3.forceLink` to position nodes and edges based on simulated physical forces. The graph displays circular nodes and curved links, with node size and color encoding additional attributes from the dataset. The code includes a PHP debug helper function, suggesting the data is processed server-side before being passed to the client for rendering.

This example visualizes a WordPress installation’s file system and directory structure, specifically highlighting the FTP configuration constant `FS_METHOD` set to `direct`. The visualization uses a force-directed graph built with `d3.forceSimulation` to position nodes representing files and folders, while `d3.geoPath` renders the connecting paths. The data appears hard-coded from the gist’s source, showing a hierarchy with the `define('FS_METHOD', 'direct')` line as a central node linked to related FTP and WordPress configuration entries.

This radial hierarchy visualization displays the dependency structure of the Flare visualization toolkit, with the dataset read from a JSON file containing module names, sizes, and import relationships. The visualization uses D3’s cluster layout combined with a bundle layout to draw curved edges that connect dependent modules in a circular arrangement. Upon mouseover, incoming links (dependants) are highlighted in brown and outgoing links (dependencies) in red, with associated nodes emphasized through font weight. The static view shows all links in blue with low opacity, and the color highlighting clarifies the directional relationships. The nodes are arranged around the circle, with labels placed outside the circumference and rotated for readability. The SVG rendering uses a radial layout with bundled edges to reduce visual clutter in the dense dependency graph of the PHP language ecosystem. The visualization is part of a gallery of data visualization examples, providing an interactive way to explore the dependency structure of the Flare visualization toolkit.

This visualization demonstrates a web application’s backend activity by rendering a chronological log of server requests and database queries as an interactive streamgraph. The example uses Ruby on Rails middleware to capture and format the log data, then relies on the `delayed_job` plugin to manage asynchronous background processing. The graph visualizes the sequence of SQL operations, controller actions, and job executions, with each event represented as a colored band along a timeline. It reveals the progression from user-facing HTTP requests to background file-processing jobs, including the point where a `Delayed::Job` fails due to a missing directory. The visualization highlights how Rails requests and background workers interleave.

Fork of Tree3

This interactive D3.js tree diagram visualizes a hierarchical dataset of failure codes and priorities from a CSV file, with nodes representing categories like functional issues and process errors. The layout uses a collapsible tree structure where clicking a node toggles its children, enabling exploration of nested relationships. Built with D3 v3, it employs `d3.layout.tree` for positioning, `d3.svg.diagonal` for curved links, and SVG transitions to animate nodes and links as the hierarchy expands and collapses. The visualization renders text labels and circles styled with CSS, with data loaded asynchronously via `d3.csv`.
