/**
 * This zero-size, overflow-visible is required to allow the chart to shrink.
 * Without it, the chart itself will fill the ResponsiveContainer, and while it allows the chart to grow,
 * it would always keep the container at the size of the chart,
 * and ResizeObserver would never fire.
 * With this zero-size element, the chart itself never actually fills the container,
 * it just so happens that it is visible because it overflows.
 * I learned this trick from the `react-virtualized` library: https://github.com/bvaughn/react-virtualized-auto-sizer/blob/master/src/AutoSizer.ts
 * See https://github.com/recharts/recharts/issues/172 and also https://github.com/bvaughn/react-virtualized/issues/68
 *
 * Also, we don't need to apply the zero-size style if the dimension is a fixed number (or undefined),
 * because in that case the chart can't shrink in that dimension anyway.
 * This fixes defining the dimensions using aspect ratio: https://github.com/recharts/recharts/issues/6245
