It's often useful to determine whether elements (e.g., tooltips) overflow the bounds of their parent container and adjust positioning accordingly. The withBoundingRects
higher-order component is meant to simplify this computation by passing in a component's bounding rect as well as its _parent's_ bounding rect.

Example usage with a component`javascript
import React from 'react';
import PropTypes from 'prop-types';
import { withBoundingRects, withBoundingRectsProps } from '@vx/bounds';const propTypes = {
...withBoundingRectsProps,
left: PropTypes.number.isRequired,
top: PropTypes.number.isRequired,
children: PropTypes.node,
};
const defaultProps = {
children: null,
};
function Tooltip({
left: initialLeft,
top: initialTop,
rect,
parentRect,
children,
}) {
let left = initialLeft;
let top = initialTop;
if (rect && parentRect) {
left = rect.right > parentRect.right ? (left - rect.width) : left;
top = rect.bottom > parentRect.bottom ? (top - rect.height) : top;
}
return (
{children}
);
}Tooltip.propTypes = propTypes;
Tooltip.defaultProps = defaultProps;
export default withBoundingRects(Tooltip);
