v1.2.2

Graphing

• Improved how node_color= colours numeric node variables

Tests

• Fixed the arc strength test depending on the BLAS

[Copilot]

Pull request overview

Updates the autograph package for the v1.2.2 release by improving how numeric node_color attributes are rendered (continuous gradients vs categorical palettes) across graphr() and grapht(), and by stabilizing arc-strength testing across BLAS implementations.

Changes:

• Treat numeric node attributes with >2 unique values as continuous and render them with a shared gradient scale (including a colourbar titled by the attribute).
• Adjust guide/legend handling so continuous fill scales keep a colourbar rather than being coerced into discrete legend keys.
• Update/extend tests to cover numeric gradients and make arc-strength tests BLAS-independent; bump version and release notes/docs.

File	Description
tests/testthat/test-grapht.R	Adds a regression test ensuring grapht() uses a continuous fill scale for numeric node_color.
tests/testthat/test-graphr.R	Adds tests for continuous gradient behavior, colourbar title, shared ranges across graphs(), and BLAS-stable arc-strength behavior.
R/grapht.R	Detects continuous node color across waves and applies a gradient scale + colourbar for numeric mappings.
R/graphr.R	Documents categorical vs continuous (measure) behavior for node_color.
R/graph_nodes.R	Applies scale_fill_gradientn() with shared limits when node color is continuous numeric.
R/graph_legends.R	Preserves colourbar guides for continuous fill scales; avoids forcing discrete legend keys.
R/graph_aes.R	Adds .is_continuous() and routes numeric measures to continuous mapping; adds shared numeric range support.
NEWS.md	Adds release notes for 1.2.2.
man/plot_grapht.Rd	Updates rendered docs to describe categorical vs gradient node coloring.
man/plot_graphr.Rd	Updates rendered docs to describe categorical vs gradient node coloring.
DESCRIPTION	Bumps package version to 1.2.2.
