An open source user-empowering data visualization Vue 3 components library for eloquent data storytelling

Docker DNS server on steroids to access DNS-over-TLS from Cloudflare, Google, Quad9, Quadrant or CleanBrowsing

QuadTree Model for generating random road network

Functions for semigraphics similar to ABC80 (setdot, clrdot, dot), TRS-80, TeleText, Text-TV, & Viewdata using 3x2 blocks, and ZX81 (plot, unplot) using 2x2 blocks.

Determination of quadrants based on angle, coordinates and others

A flutter application showing the usage of simple CustomPaint and CustomPainter to draw a quadrant chart with dynamically populated data (icons) inside each quadrant.

Another Intro To C assignment (this one tells what quadrant a point is in based on its coordinates)

The QDC Security Lab is designed to teach the fundamentals of modern cryptography by demonstrating how algorithms evolve to fix structural weaknesses. Users can experiment with three generations of the QDC cipher, hide data using steganography, and analyze security metrics like the Avalanche Effect and Frequency Analysis.

This project visualizes AI tools using a quadrant-based layout, inspired by the Gartner Magic Quadrant.

Approximate Angles of any vector using it's quadrant and a radial slice index. Useful for rotation invariant indexing of a dynamic stream of x/y points. For instance, in creating pooled rotation-scale-translation invariant histograms.
