7 years ago I managed to make it worked using the following code. I will try to make it as plugin the next days but you may want to try:
` var zoom = d3.behavior.zoom().scaleExtent([1, 8]).on("zoom", move); DatamapObject.svg.call(zoom); var g= d3.select("g") function move() { var t = d3.event.translate, s = d3.event.scale; t[0] = Math.min(width / 2 (s - 1), Math.max(width / 2 (1 - s), t[0])); t[1] = Math.min(height / 2 (s - 1) + 230 s, Math.max(height / 2 (1 - s) - 230 s, t[1])); zoom.translate(t); g.style("stroke-width", 1 / s).attr("transform", "translate(" + t + ")scale(" + s + ")"); }
`
On hovering over a country the country should zoom out. Is this feature currently supported?
