@Composable

fun SchemeView(state: XYCanvasState, features: FeatureGroup<XY>, modifier: Modifier = Modifier.fillMaxSize())

@Composable

fun SchemeView(features: FeatureGroup<XY>, initialViewPoint: ViewPoint<XY>? = null, initialRectangle: Rectangle<XY>? = null, config: ViewConfig<XY> = ViewConfig(), modifier: Modifier = Modifier.fillMaxSize())

A builder for a Scheme with static features.

@Composable

fun SchemeView(initialViewPoint: ViewPoint<XY>? = null, initialRectangle: Rectangle<XY>? = null, config: ViewConfig<XY> = ViewConfig(), modifier: Modifier = Modifier.fillMaxSize(), buildFeatures: FeatureGroup<XY>.() -> Unit = {})

Draw a scheme using convenient parameters. If neither initialViewPoint, noe initialRectangle is defined, use map features to infer view region.
