visual_models mounts a self-contained D3-powered association graph at any path in your Rails app. It introspects ApplicationRecord (and, optionally, ActiveModel-only classes) at runtime, walks every reflection (belongs_to, has_one, has_many, has_many :through, has_and_belongs_to_many, polymorphic), and renders an interactive force-directed graph with search, zoom, drag-to-rearrange, position persistence, and a click-through details panel. Ships with zero asset-pipeline dependencies — D3 and Stimulus are loaded from CDN. Recommended for development environments only.
