Pull request

Description

This PR introduces two new composables in pillarbox-demo-shared: LineChart and BarChart. As their names suggest, they are meant to display simple line- and bar-charts.

Usage

The most basic usage for each component looks like this:

LineChart(
    data = listOf(12f, 4.5, 8.2f, 24.3f, 1.9f),
	modifier = Modifier.size(400.dp), // Modifier is not mandatory, but `Canvas` requires a size to be set
)

BarChart(
    data = listOf(12f, 4.5, 8.2f, 24.3f, 1.9f),
	modifier = Modifier.size(400.dp), // Modifier is not mandatory, but `Canvas` requires a size to be set
)

Each component provides a set of options to customize how it is displayed (color, stroke width, spacing, ...).

The charts doesn't work in a container that has a fixed size ? For example

Column(modifier = Modifier.fillMaxWidth(0.5f)){
    LineChart(...)
}

LineChart and BarChart use Canvas internally, which doesn't have a size by default. So the Modifier of each chart should be used to set one (using something like .size(), .height()/.width(), .filleMaxWidth(), ...).
