Graphviz Rendering Scripts

This repository contains two Bash scripts to automatically render Graphviz .dot files into both SVG and PNG formats.

• render_graphs.sh: Renders a single .dot file into both SVG and PNG.
• render_graphs_all.sh: Finds and renders all .dot files in the current directory by calling render_graphs.sh.

Installation

Before using the scripts, you need to have Graphviz installed on your system. Graphviz provides the dot command used for rendering .dot files.

Install Graphviz on Linux

On most Linux distributions (Ubuntu/Debian-based), you can install Graphviz using the package manager:

sudo apt-get update
sudo apt-get install graphviz

For Fedora-based distributions:

sudo dnf install graphviz

For Arch Linux:

sudo pacman -S graphviz

Install Graphviz on macOS

If you are using macOS, you can install Graphviz using Homebrew:

brew install graphviz

How to Use the Scripts

1. render_graphs.sh

This script renders a single .dot file into both SVG and PNG formats.

Usage:

./render_graphs.sh <input_file.dot>

Example:

./render_graphs.sh my_graph.dot

This will generate my_graph.svg and my_graph.png in the same directory as the .dot file.

2. render_graphs_all.sh

This script finds all .dot files in the current directory and calls render_graphs.sh to render each one.

Usage:

./render_graphs_all.sh

Example:

Simply run the script in the directory containing .dot files:

./render_graphs_all.sh

This will generate SVG and PNG files for all .dot files in the directory.

Script Details

• render_graphs.sh: This script takes one argument, the name of the .dot file, and outputs both an SVG and a PNG of the graph.

• render_graphs_all.sh: This script loops through all .dot files in the current directory and calls render_graphs.sh to process each one.

Make Scripts Executable

After downloading or creating the scripts, make them executable by running:

chmod +x render_graphs.sh
chmod +x render_graphs_all.sh
