## Features

- **3D Visualization**: Renders Graphviz dot files as interactive 3D scenes
- **Node Types**: Different shapes and colors for various node types (organization, team, user, etc.)
- **Hierarchical Layout**: Automatic vertical and radial positioning based on node levels
- **Interactive Navigation**: 
  - Arrow keys for movement
  - Shift+Arrow keys for camera rotation
  - +/- keys for zoom (Mac-friendly)
- **Smart Label Visibility**: 
  - Labels only show for nearby nodes (configurable distance)
  - Hold 'L' to temporarily show all labels
  - Labels fade as they approach visibility distance
- **Node Search**: 
  - Press '/' to open search mode
  - Type to filter and highlight matching nodes
  - Press ESC to close search
  - Highlights slowly fade out over 20 seconds
- **Unix Philosophy**: Supports both file input and stdin piping
- **Clear Text Labels**: Node labels rendered as overlay text for clarity

## Installation

### Prerequisites

- Rust 1.75 or higher (2024 edition)
- System dependencies for Bevy (automatically handled on most platforms)

### Building from crates.io

```
cargo install dotspace
```

### Building from Source

```bash
git clone https://github.com/navicore/dotspace.git
cd dotspace
make build
```

The binary will be available at `target/release/dotspace`.

## Usage

### Basic Usage

```bash
# Visualize a dot file
dotspace graph.dot

# Pipe from another command
cat graph.dot | dotspace

# Generate and visualize on the fly
echo "digraph { A -> B -> C }" | dotspace
```

### Command Line Options

```bash
dotspace [OPTIONS] [FILE]

Arguments:
  [FILE]  Optional dot file path. If not provided, reads from stdin

Options:
  -d, --distance <DISTANCE>     Initial camera distance from center [default: 25.0]
  -s, --speed <SPEED>           Camera movement speed [default: 5.0]
  -v, --label-distance <DIST>   Label visibility distance [default: 15.0]
  -h, --help                    Print help
  -V, --version                 Print version
```

### Controls

| Key | Action |
|-----|--------|
| Arrow Keys | Move camera forward/backward/left/right |
| Shift + Arrow Keys | Rotate camera around center |
| + / - | Zoom in/out |
| PageUp / PageDown | Alternative zoom controls |
| L (hold) | Show all labels temporarily |
| / | Open search (type to filter nodes) |
| ESC | Close search mode |
| Q | Exit application |

## Dot File Features

dotspace supports standard Graphviz dot syntax with additional attributes for 3D visualization:

### Node Types

Specify node types for different shapes and colors:

```dot
digraph Organization {
    "CEO" [type="organization", level="3"];
    "CTO" [type="team", level="2"];
    "Dev1" [type="user", level="1"];
    
    "CEO" -> "CTO";
    "CTO" -> "Dev1";
}
```

Available node types:
- `organization` - Red cube (large)
- `lob` (Line of Business) - Orange cylinder
- `site` - Blue torus
- `team` - Green sphere
- `user` - Purple capsule (small)
- (default) - Gray sphere

### Hierarchical Levels

Use the `level` attribute to control vertical positioning:

```dot
digraph Hierarchy {
    "Level3" [level="3"];
    "Level2" [level="2"];
    "Level1" [level="1"];
    "Ground" [level="0"];
}
```

## Examples

The repository includes several example dot files in the `examples/` directory:

```bash
# Organizational hierarchy
dotspace examples/hierarchy.dot

# Network topology
dotspace examples/network_topology.dot

# Software architecture
dotspace examples/software_architecture.dot

# Simple directed graph
echo 'digraph { rankdir=LR; A -> B -> C -> D; B -> D; }' | dotspace
```

## Development

### Running Tests

```bash
make test
```

### Linting

```bash
# Run clippy with CI settings
make clippy

# Auto-fix clippy warnings
make clippy-fix

# Format code
make fmt
```

### Development Workflow

```bash
# Full check (format, lint, test, build)
make all

# Run with example file
make run

# Run with stdin example
make run-stdin
```

## Architecture

dotspace is built with:
- **Bevy 0.16**: Modern Rust game engine for 3D rendering
- **petgraph**: Graph data structure management
- **clap**: Command-line argument parsing

The visualization uses:
- Custom dot file parser (handles documented Graphviz DSL)
- Hierarchical layout algorithm with radial distribution
- Bevy's entity-component system for interactive 3D scenes
