Move the `visualize(::AbstractNamedGraph, ...)` overload that previously lived in ITensorNetworks.jl (where it was type piracy) into NamedGraphs as a package extension keyed on ITensorVisualizationBase. The method delegates to `visualize(position_graph(graph), ...)` with optional `vertex_labels_prefix` for labeling. Bumps version to 0.11.1.

## Summary - Adds a new package extension `DataGraphsITensorVisualizationBaseExt`, keyed on `ITensorVisualizationBase`, that overloads `visualize(::AbstractDataGraph, ...)` to delegate to `visualize(underlying_graph(graph), ...)`. This method previously lived in `ITensorNetworks.jl/src/visualize.jl` as type piracy (DataGraphs owns the type but the method was defined elsewhere); moving it here removes the piracy on `AbstractDataGraph`. - Adds a `test_itensorvisualizationbase_ext.jl` smoke test that confirms the extension loads and the method is dispatchable. - Bumps the Julia compat floor to `1.10` to match the rest of the ITensor ecosystem. - Bumps version to `0.4.1`. Companion to [NamedGraphs.jl#166](ITensor/NamedGraphs.jl#166) (same pattern for `AbstractNamedGraph`). A follow-up PR will drop the stale methods from `ITensorNetworks.jl/src/visualize.jl`. --------- Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

Replace the in-source `visualize(::AbstractITensorNetwork, ...)` method (in `src/abstractitensornetwork.jl`) and the two type-piracy methods on `AbstractNamedGraph` / `AbstractDataGraph` (in `src/visualize.jl`) with a single `ITensorNetworksITensorVisualizationBaseExt` package extension that overloads `visualize(::AbstractITensorNetwork, ...)` only. The type-piracy methods migrate upstream: - `NamedGraphs.jl` v0.11.1 (PR ITensor/NamedGraphs.jl#166) adds the `AbstractNamedGraph` overload via its own `NamedGraphsITensorVisualizationBaseExt`. - `DataGraphs.jl` v0.4.1 (PR ITensor/DataGraphs.jl#119) adds the `AbstractDataGraph` overload via `DataGraphsITensorVisualizationBaseExt`. Each method now lives in the package that owns the type, removing the piracy. The extensions are all keyed on the registered standalone `ITensorVisualizationBase` package; the methods overload `ITensorVisualizationBase.visualize`, which shares its binding with `ITensors.ITensorVisualizationCore.visualize` (the in-tree submodule) so rendering backends pick them up. Bumps `[compat]` floors to `NamedGraphs = "0.11.1"` and `DataGraphs = "0.4.1"`. Co-Authored-By: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

## Summary - Adds `ITensorNetworksITensorVisualizationBaseExt`, a new package extension keyed on `ITensorVisualizationBase`, holding the `visualize(::AbstractITensorNetwork, ...)` overload that previously lived in `src/abstractitensornetwork.jl`. - Drops `src/visualize.jl` entirely. The two methods it held (overloads of `visualize` on `AbstractNamedGraph` and `AbstractDataGraph`, which were type piracy from here) move upstream into the packages that own those types: see [ITensor/NamedGraphs.jl#166](ITensor/NamedGraphs.jl#166) and [ITensor/DataGraphs.jl#119](ITensor/DataGraphs.jl#119). - Bumps `[compat]` floors to `NamedGraphs = "0.11.1"` and `DataGraphs = "0.4.1"` to ensure the upstream extensions are present. - The extensions are keyed on the registered standalone `ITensorVisualizationBase` package. The methods overload `ITensorVisualizationBase.visualize`, which shares a binding with `ITensors.ITensorVisualizationCore.visualize` (the in-tree submodule), so rendering backends pick them up. Adds `test/test_itensorvisualizationbase_ext.jl` covering the new method. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>

…21.2 (#369) ## Summary Backport of #367 onto the new `release-0.21` branch. Replaces the in-source `visualize(::AbstractITensorNetwork, ...)` method (in `src/abstractitensornetwork.jl`) and the two type-piracy methods on `AbstractNamedGraph` / `AbstractDataGraph` (in `src/visualize.jl`) with a single `ITensorNetworksITensorVisualizationBaseExt` package extension that overloads `visualize(::AbstractITensorNetwork, ...)` only. The type-piracy methods migrate upstream: - `NamedGraphs.jl` v0.11.1 ([#166](ITensor/NamedGraphs.jl#166)) adds the `AbstractNamedGraph` overload via its own `NamedGraphsITensorVisualizationBaseExt`. - `DataGraphs.jl` v0.4.1 ([#119](ITensor/DataGraphs.jl#119)) adds the `AbstractDataGraph` overload via `DataGraphsITensorVisualizationBaseExt`. ## Motivation for backporting Once NamedGraphs v0.11.1 and DataGraphs v0.4.1 register, any user on legacy ITensorNetworks v0.21.x alongside the new NamedGraphs/DataGraphs would hit method-overwrite warnings on the two type-pirated `visualize` methods. v0.22 may take a while to ship (its prerelease accumulator is still receiving changes), so we publish a v0.21.2 patch carrying the equivalent fix. ## Changes - Adds `ext/ITensorNetworksITensorVisualizationBaseExt/`. - Removes `src/visualize.jl` (and its `include` from `src/ITensorNetworks.jl`). - Removes the `visualize(::AbstractITensorNetwork, ...)` block from `src/abstractitensornetwork.jl`. - Adds `ITensorVisualizationBase` to `[weakdeps]` / `[extensions]` / `[compat]`. - Bumps `[compat]` floors: `NamedGraphs = "0.11.1"`, `DataGraphs = "0.4.1"`. - Bumps package version `0.21.1` → `0.21.2`. ## Release-branch workflow This is the first PR against the new `release-0.21` branch, modeled on Julia's `release-X.Y` convention (simplified — no `backports-release-X.Y` staging tier, since we expect only 1–2 backports before v0.22 ships). After merge, registration needs to be triggered manually via a `/register <merge-sha>` commit comment on the merge commit (the `Registrator.yml` workflow's `push` trigger only fires on `main`/`master` by default; the `issue_comment` path uses `force=true` and works regardless of branch). ## Status CI will be red until NamedGraphs v0.11.1 and DataGraphs v0.4.1 actually land in the registry. Opening the PR now mostly for tracking. Co-authored-by: Claude Opus 4.7 (1M context) <noreply@anthropic.com>
