The chart collection builds on ChartGalaxy. Real-image source channels include Statista, Visual Capitalist, Pinterest collections, Flickr, and other infographic publishers. Each record's `source_channel` preserves the collection identity; its reference fields preserve available source URLs or upstream archive members. `source_counts.json` reports collection counts. A collection channel or archive host is not necessarily the original copyright owner.

Real images are referenced only. This repository does not redistribute their image binaries or grant rights to those third-party works. Original website URLs are unavailable for some records; those records retain explicit references to upstream archive members instead.

Synthetic images from the `layout` and `nb2` tracks are included alongside their annotations. Embedded brands, logos, and other third-party assets remain subject to their owners' rights and applicable source terms. The license on contributed annotations does not relicense underlying third-party material.

This release contains dataset files and documentation only.
