## Description

Chessdiag allows you to display clean and customizable chess diagrams directly in
your WordPress content.

Use the shortcode with a Chessdiag position code between the opening and closing
tags.

Example:

[diag]mrmnmbmqmkmbmnmr8mp32s8prnbqkbnr[/diag]

Features:

 * Display chess diagrams from Chessdiag position codes
 * Custom board size
 * Highlight squares
 * Draw arrows
 * Optional coordinates
 * Clickable board (optional)

The diagrams are generated via an external service.

### External Services

This plugin loads images from:

https://chessdiag.org/

When a diagram is displayed, the visitor’s browser requests an image from this service.

The request includes the encoded chess position (FEN) and display parameters.

No personal data is intentionally collected by the plugin itself. However, standard
web requests may include technical information such as IP address or browser details,
depending on the server configuration.
