SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

It helps coding agents quickly transform structured data (JSON) into interactive, navigable visualizations directly inside the terminal, avoiding the friction of generating and interpreting static charts elsewhere.

Core Features & Use Cases

Interactive terminal rendering: Opens a split-pane viewer with keyboard navigation (select with Enter, quit with q).
Multiple visualization types: Supports bar, line, flow diagrams, trees, tables, grids, timelines, heatmaps, stacked bars, and sequence diagrams from a consistent JSON input.
Terminal-aware output: Uses Kitty-style SVG→PNG graphics in capable terminals and falls back to Ink/blessed UIs otherwise.

Quick Start

Ask your AI to visualize your data by sending valid visualization JSON to the terminal-visualizer tool in a heredoc.

FAQPage Schema

How do I visualize JSON data directly in the terminal?▼

To visualize JSON data in the terminal, you can render interactive charts and diagrams by passing a valid visualization payload to a terminal-visualizer tool, which outputs a split-pane TUI with keyboard navigation.

What types of diagrams can I generate from JSON in a terminal UI?▼

Generating terminal UI diagrams from JSON supports bar, line, flow diagrams, trees, tables, grids, timelines, heatmaps, stacked bars, and sequence diagrams to communicate data structure, trends, and relationships.

Does terminal visualization work with Kitty and other TUI backends?▼

Terminal visualization works with Kitty backends by rendering SVG-to-PNG graphics, and falls back to Ink or blessed TUI libraries automatically based on detected terminal capabilities.

How do I navigate interactive terminal charts generated from JSON?▼

Navigating interactive terminal charts requires using keyboard controls within the split-pane viewer, where you can select items with Enter and quit the visualization interface with q.

Can AI coding agents use terminal visualization to display architecture and heatmaps?▼

AI coding agents can display architecture, timelines, and heatmaps by transforming structured JSON into pixel-perfect terminal visuals, allowing AI to communicate structure and relationships without external static charts.

What is the best way to avoid static charts when analyzing JSON in a terminal?▼

The best way to avoid static charts when analyzing JSON in a terminal is using an interactive TUI visualizer that renders navigable diagrams directly in the console and maps selections back to Bash-readable results.
