Obsidian Flowchart Plugin

This is a custom plugin for rendering flowcharts in Obsidian using flowchart.js. It allows users to insert and render flowcharts directly within Obsidian notes using a dedicated code block syntax.

Features

• Renders flowcharts using flowchart.js syntax within Obsidian notes.
• Supports customization of flowchart styles, such as line width, font size, colors, and element styling, directly from the plugin settings.
• Adjustable settings for each part of the flowchart, including start and end symbols, decision conditions, operations, and more.
• Provides an easy way to create interactive and visually appealing diagrams in your notes.

How to Use

1. Open a note in Obsidian and add a flowchart code block, like this:

   ```flowchart
   st=>start: Start
   op=>operation: My Operation
   cond=>condition: Yes or No?
   e=>end: End
   
   st->op->cond
   cond(yes)->e
   cond(no)->op
   ```

2. The plugin will render the flowchart according to the configuration specified in the plugin settings. You can check more examples here: Flowchart Plugin test.

Plugin Settings

The plugin includes various settings that allow you to customize the appearance of the flowchart:

• Line Width: Controls the width of lines in the flowchart.
• Font Size: Sets the font size for text within the flowchart.
• Font Color: Changes the color of the font.
• Line Color: Sets the color of the lines connecting elements.
• Element Color: Adjusts the color of the shapes around text.
