• Add direct encoded-array overloads for Scatter, Bar, StackedBar, Column, StackedColumn, Heatmap, Histogram2D, and Scatter3D, reusing Plotly.NET.EncodedTypedArray.

• Add ParallelCoord / ParallelCategories conveniences accepting label/encoded-value pairs. Existing SPLOM and Sankey wrappers also accept shared dimension/node/link objects containing encoded values.

• Add a Sankey label/link convenience with NodeAlign for Left, Right, Center, or Justify alignment.

• Document and test C# factory syntax for 1D arrays and shaped matrices. Additional direct encoded wrappers remain outside this release's selected C# scope; existing plain overloads are preserved.

• Split the C# chart implementation and tests into per-chart files without changing the existing API.

• bump version range of Plotly.NET to [6.0.0, 7.0.0)

• Breaking: Plotly.NET.CSharp assemblies are no longer strong-named. See the Plotly.NET 6.0.0 release notes for context and migration options.

• Dev tooling: target framework updated to net10.0; xunit 2.9.3, xunit.runner.visualstudio 3.1.5, coverlet.collector 8.0.1

• Add C# wrapper for Chart.SingleStack thanks @TheKiiiing!

• bump version range of Plotly.NET to [5.0.0, 6.0.0)
• Reflect relevant API changes in Plotly.NET 5.0.0 (e.g. in Chart.Grid)

• bump version range of Plotly.NET to [4.1.0, 5.0.0)

• BREAKING: Fix a typo in WithMapbox and WithMapboxStylemethod names, thanks hdavid333!

• Add WithLegend and WithLegendStyle extension methods to GenericChart

• Update package to work with Plotly.NET 4.0
• use strict dependency range to prevent major version increases from Plotly.NET from breaking dependent packages.
