Majority Graph Designer

Majority Graph Designer is a simple web application for building majority (directed) graphs commonly used in voting and preference systems.
It allows you to create nodes, connect them with directed edges, use scientific and LaTeX-style notation, and export publication-ready diagrams.

Features

• Add nodes displayed as circles
• Create directed edges between nodes
• Edit or delete edges through an interactive table
• Support for scientific and LaTeX-like expressions
  (subscripts, superscripts, \frac{a}{b}, symbols such as λ, χ, etc.)
• Export diagrams as JPG, PNG, or SVG
• Save and load graphs using JSON files
• Rendered in Times New Roman
• Black-and-white output suitable for papers and reports
