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.

Features:
- Display chess diagrams from Chessdiag position codes

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.
