Treemap

A treemap.

Usage

from dataviz_mojo import treemap
from dataviz_mojo.plot import save

def main() raises:
    var ids: List[String] = ["root", "src", "docs", "main.py", "utils.py", "guide.md", "api.md"]
    var parent_ids: List[String] = ["", "root", "root", "src", "src", "docs", "docs"]
    var sizes: List[Float64] = [0.0, 0.0, 0.0, 45.0, 20.0, 12.0, 8.0]

    var c = treemap(ids, parent_ids, sizes)
    save(c, "docs/src/examples/out_treemap.svg")

Args:

• ids: Every node’s unique id, flattened (not nested), one entry per node.
• parent_ids: Each node’s parent id (must be a value present in ids, or empty for the single root); paired with ids[i].
• values: Each leaf node’s area; an internal node’s area is the sum of its descendants’ – see Plot.encode_hierarchy()’s docstring for the exact rule.
• theme: Full styling knobs beyond this function’s own parameters (colors, margins, fonts, gridlines, …) – see Theme’s docstring.
• width: Pixel width of the returned Plot (.size()).
• height: Pixel height of the returned Plot (.size()).
• title: The chart’s title, shown above the plot.
• subtitle: A secondary line shown under the title.
• x_title: The x-axis caption.
• y_title: The y-axis caption.
