问Leaflet热图:如何使用随缩放缩放的特定于点的半径来绘制点？

EN

 //just some sample single location
text = "lat;long;walk\n39.1101;-84.5758;3";

var lines = text.split("\n");
var heatData = [];
for (var i=1; i<lines.length; i++) {
    var parts = lines[i].split(",");
    heatData.push( [ parts[0], parts[1], 1. ]  )
}

var heat = L.heatLayer(heatData, {radius: 20, blur: 10, scaleRadius: true, max: 0.1, max_zoom: 20 }).addTo(map);
