click point invert zoom react simple map

//And, the onClick factory for Geography-ies, that will take Map's this.getScale as scale argument:

function onGeographyClick (scale, projection, onCoordinatesClick) {
    const gp = geoPath().projection(projection)

    return function (geo, evt) {
        const dim = evt.target.getBoundingClientRect()
        const cx = evt.clientX - dim.left
        const cy = evt.clientY - dim.top
        const [orgX, orgY] = gp.bounds(geo)[0]

        onCoordinatesClick(projection.invert([orgX + cx / scale(), orgY + cy / scale()]))
    }
}
