Bug: Chart hover broken due to delaunator package version conflict

[galkremer1]

Describe the problem Hovering over charts does not display the expected label. Instead, an error TypeError: _delaunator.default is not a constructor is thrown. This issue is caused by a version conflict with the delaunator package, where @patternfly/react-topology depends on version 5.0.1, while @patternfly/react-charts uses a dependency (delaunay-find) that expects an older version (4.0.1).

How do you reproduce the problem?

1. Navigate to a page containing a chart component that utilizes the @patternfly/react-charts library.
2. Ensure @patternfly/react-topology is also installed in the project.
3. Hover your mouse over the chart.

Expected behavior When hovering over the chart, the tooltip/label should appear, displaying the data point details without any errors.

Is this issue blocking you? Yes, this issue is a critical blocker as it breaks the primary interaction for data visualization charts, making it impossible for users to inspect data points.

A workaround is to restrict the delaunator dependency to version 4.0.1 in the project's package.json file to resolve the conflict.

What is your environment?

• OS: Macos 15.6
• Browser: Chrome
• Version: 139.0.7258.128 (Official Build) (arm64)

What is your product and what release date are you targeting? Product: kubevirt-plugin

@dlabrecq could we bump the version of delaunay-find in react-charts to match that in topology?

Victory's VoronoiContainer already appears to be using the latest [email protected] package, which is responsible for [email protected].

See https://github.com/FormidableLabs/victory/blob/main/packages/victory-voronoi-container/package.json

That said, using npm overrides in package.json installed [email protected] for me.

  "overrides": {
    "delaunator": "^5.0.1"
  },
