AI-generated ASCII diagrams

This article discusses the utility and charm of AI-generated ASCII diagrams, which are compact, embeddable in source code and markdown, and prevent diagram-code separation. The author tests Claude's ability to create such diagrams, reproducing graphs from a prior post on the graph imbalance theorem, a complex network diagram, and a DES Feistel network. The post highlights the tedium of manual ASCII diagram creation and how AI mitigates it, while noting potential rendering issues in different formats. It's a practical look at using AI for technical documentation.
