Description
Decomp Concept Graph builds an interactive, graph-based knowledge portal from your WordPress content:
- A dedicated “Hub Entries” content type with hierarchical categories, proficiency levels and bidirectional relationships.
- A D3.js graph viewer with global search, a category menu and article feeds (Latest and Featured).
- Article widgets: breadcrumbs, table of contents, related articles and a floating graph window centered on the current node.
- Multilingual: automatic integration with Polylang and WPML (the graph and texts follow the active language); monolingual when neither is active.
- Tabbed admin panel (Welcome, Hub, Metrics, Sync/Examples, Support) with one-click sample data and Markdown export.
Gutenberg blocks
- Hub Dashboard — the full portal: search, category menu, the interactive graph and the Latest/Featured feeds.
- Hub Entries — the per-entry widgets: breadcrumbs, table of contents, related entries and a focused graph.
Shortcodes
- [dcgraph_portal_dashboard] – full Dashboard.
- [dcgraph_article_widgets] – article widgets.
External Services
This plugin integrates the Freemius SDK (a third-party plugin licensing and analytics service) to provide optional, opt-in usage diagnostics, to manage your account and license for the separate premium add-on, and to display its pricing/checkout when you choose to open it. The plugin is fully functional without contacting this service; no personal data is sent unless you opt in or actively use the account/checkout flows.
- Service: Freemius (https://freemius.com).
- Endpoints contacted: api.freemius.com, wp.freemius.com and checkout.freemius.com.
- When it is contacted: (a) only if you grant opt-in consent, for anonymous environment diagnostics; (b) when you connect an account or activate/validate a license for the premium add-on; (c) when you open the pricing or checkout screen.
- Data sent in those cases: your site URL and domain, the plugin and WordPress/PHP versions, and – only if you opt in or sign in – your administrator email and basic environment details; plus the license key when you activate a license.
- Terms of Use: https://freemius.com/terms/ – Privacy Policy: https://freemius.com/privacy/
The D3.js library (BSD-3-Clause, GPL-compatible) is bundled locally; it is not loaded from any external CDN.

FAQ
-
Do I need Polylang or WPML?
-
They are optional. With Polylang or WPML installed, multilingual support is automatic – the graph and texts follow the active language; without them the plugin runs in monolingual mode. Do not use both at the same time.
-
How do I connect two entries?
-
In an entry’s editor, check the related entries in the relationships metabox; the link is created bidirectionally.
-
Does it load D3.js from a CDN?
-
No. D3.js (BSD-3-Clause, GPL-compatible) is bundled locally – both the minified runtime (assets/js/d3.v7.min.js) and the full, unminified source (assets/js/d3.v7.js) ship inside the plugin. Nothing is loaded from a CDN. The library’s home is https://github.com/d3/d3.
-
Is there a paid version?
-
A separate, optional premium add-on with extra features is available from the author at https://decomp.finance/en/decomp-concept-graph/. It is not required – this plugin is fully functional on its own.

Changelog
1.0.9
- Fix: the “Upgrade” (Plans and Pricing) screen rendered blank. The bundled Freemius SDK is updated from 2.13.2 to 2.13.4, whose pricing app correctly selects the product’s currency.
- Tested up to WordPress 7.1.
1.0.8
- Maintenance: version alignment with the premium add-on. No functional change to the free plugin.
1.0.7
- Security: integer request parameters now use absint() for clearer, tool-recognized sanitization.
1.0.6
- Packaging: the full unminified D3.js source now ships alongside the minified runtime, and development-only files are excluded from the distributed package.
- Security: additional unslashing/sanitization hardening on admin form inputs.
1.0.5
- WordPress.org compliance: the free build now contains no premium or locked-feature code. Multiple Hubs, My Vault, the individual blocks (Search/Selector/Graph/Viewer), Markdown import and the custom color/styling controls are no longer part of the free package – they ship only in a separate premium build (the free build keeps a fixed default look). The free plugin is a fully-functional single knowledge base.
- Security: hardened input sanitization, validation and escaping across the plugin (relationship saving, search, ZIP/export handling, settings inputs).
1.0.4
- WordPress.org compliance: the free build contains only the free feature set; feature availability is decided solely by code presence (no license-based gating).
- The free admin Help/Support tab documents only the features included in the free build.
- Security: the public graph endpoint and the embedded front-end graph data only ever include published content. Translated entries and linked relationships are verified as published before they are exposed, so no draft or private content can leak.
1.0.1
- Security: entry titles and descriptions are sanitized before they are drawn in the graph, cards and search; the Viewer card template is escaped.
- Multilingual: graph relationships now sync correctly when an entry is edited in a secondary language; the dashboard respects the active site language.
- Fixes: a duplicate category box in the editor, “nodes without links” detection, and a script clash when a Dashboard and an Article block share the same page.
1.0.0
- Initial release: entries CPT, category and level taxonomies, bidirectional relationships, local D3 graph, multilingual (Polylang/WPML), Hub Dashboard and Hub Entries blocks, shortcodes, tabbed admin panel and Markdown export.
