# `PhiaUi.Components.Data.BarTotals`
[🔗](https://github.com/charlenopires/PhiaUI/blob/v0.1.17/lib/phia_ui/components/data/bar_totals.ex#L1)

Sum labels rendered above stacked bar groups — pure SVG, zero JS.

Inspired by Nivo's BarTotals layer. Renders `<text>` elements showing
the total value at the top of each stacked bar group.

Designed to be composed inside a bar chart or xy_chart SVG.

## Examples

      %{x: 72.0, y: 20.0, label: "350"},
      %{x: 152.0, y: 30.0, label: "280"}
    ]} />
