Hacker Atlas is a tool that maps and visualizes the topics discussed on Hacker News, allowing users to browse topics and explore connections between them.
A tool that compiles custom fonts where each LLM token occupies equal width, enabling visual representation of tokenization in Discord and Slack. Users select a base font and tokenizer, compile the font, and install it alongside a theme or userscript to display messages with uniform token widths.
Choreoglyphs is a new invisible writing system that visualizes the hand movements created when using swipe keyboards on phones. Each word is represented by the choreographic path connecting letters, making previously invisible gesture patterns visible.
Disktree is a treemap visualization tool for Omarchy that helps users identify and remove files consuming disk space. It scans directories, displays them as nested mosaics sized by actual disk usage, and allows safe deletion with review before commitment.
SunCalc is a web tool that visualizes the sun's movement and sunlight phases for any date and location, displaying sunrise/sunset times, solar trajectory, and daily sunlight variations through an interactive interface.
A live visualization tool for variational quantum circuits applied to deep Q-learning on a grid world environment. The project includes an interactive GUI showing circuit parameters, gradients, and policy performance, with exact Bellman value iteration as a reference baseline. Developed during a 2024 internship at Porto University.
Lini is a unified language for creating diagrams, charts, schematics, and drawings with support for various layout types including flowcharts, sequence diagrams, and entity-relationship diagrams using a declarative syntax with styling and directional components.
Depglobe is a browser-based tool that visualizes the maintainers of a software repository's dependencies on an interactive 3D globe. It supports multiple package managers including npm, PyPI, Go, and Cargo, requiring no authentication token.
This article explains how the Fourier transform can be used to draw complex shapes by combining rotating circles (epicycles) at different frequencies, radii, and phases. The technique is demonstrated with examples like drawing a llama using 1024 circles, and the article introduces the mathematical foundations including complex numbers and frequency domain analysis.
A Chicago resident created an automated system to fetch and visualize their annual transit card data from the CTA's Ventra system after noticing other transit agencies offered yearly wrapped experiences. The project involved reverse-engineering the Ventra web API to extract usage history, then building data analysis and visualization tools to generate weekly and monthly transit summaries.
Bubs.co presents OzBrain, a shared knowledge platform that visualizes user information as a dynamic "Live Brain Signature" with colors and motion, allowing multiple AI agents to access and build upon the same knowledge base without redundant context transfers.
Volum is an open-source desktop application that creates a searchable visual library of 3D model files (STL, OBJ, 3MF, STEP) without moving or uploading them. Available for macOS, Linux, and Windows, it indexes files locally, generates previews, reads printer and filament metadata, and supports collections, tags, and cost calculations.
Fractalysis is an online interactive viewer for exploring the Mandelbrot set with infinite zoom capability, offering customizable colors, shadows, and position controls along with real-time statistics on iterations and precision.
Heimdall is a code visualization tool that generates interactive dependency maps from any codebase, helping developers understand complex software architecture without reading code file by file. It runs locally and offline, supporting 16 languages, with a CLI interface for LLM integration and AI-powered development workflows.
Arcentry is a tool for creating beautiful 2D and 3D infrastructure diagrams with 800+ components covering cloud providers, on-premises systems, and open-source technologies. Users can design diagrams manually, import from Terraform or CloudFormation, or use AI Chat to generate them automatically, with real-time updates via API for live monitoring visualization.
Nvitop is an interactive NVIDIA GPU process monitoring tool that provides a colorful, feature-rich interface for tracking GPU devices and processes. It offers advantages over similar tools like nvidia-smi through efficient querying, responsive interactivity, cross-platform support for Linux and Windows, and integrable APIs for developers.
A demo showcasing an embeddable Mermaid flowchart editor built using JointJS and Bryntum, with features available in both commercial JointJS+ and open-source JointJS packages.
WebGCM is a global climate model that runs in web browsers using WebGPU, simulating atmospheric dynamics, ocean circulation, sea ice, and terrain across 41,000 cells. Users can visualize weather patterns, wind currents, temperature, and precipitation in real time, with fallback to CPU rendering for browsers without WebGPU support.
A developer created a Pomodoro timer that manipulates perception of time by using a cubic Bézier curve inspired by MrBeast's ad segment progress bars, which fill quickly at first then slow down. Both the progress bar and countdown follow the same curve to maintain the illusion that time passes faster than it actually does.
Code Graph View is a VS Code extension that visualizes codebases as interactive call graphs, allowing developers to trace execution paths, analyze git changes, and generate curated context for AI assistants like Claude Code and GitHub Copilot in a single click.
