@chart-kit/core

Renderer-agnostic core utilities for React Native Chart Kit.

This package owns:

• data normalization
• series models
• scales, domains, and ticks
• layout calculations
• geometry generation
• interaction math
• theme tokens
• accessibility summaries

Boundary rules:

• Do not import react, react-native, or react-native-svg.
• Keep functions deterministic and unit-testable.
• Return plain data models for renderers to consume.
• Add public API intentionally; current exports are the first data normalization primitives.

Current exports:

• normalizeCartesianData
• normalizeLegacyLineData
• normalizeLegacyPieData
• normalizeLegacyProgressData
• normalizeLegacyStackedBarData
• normalizeLegacyContributionData
• buildLinePath

• buildLineSeriesGeometry

• getDecimatedLinePathSegments
• splitDefinedSegments
• resolveNumericDomain
• resolveTimeDomain
• createLinearScale
• createTimeScale
• createBandScale
• createPointScale
• generateLinearTicks
• generateTimeTicks
• solveChartBoxes
• calculateAutoPadding
• buildLayoutDebugModel
• solveLabelCollision
• layoutLegend
• placeTooltip
