d3js v5 + topojson v3 Access to the object's properties in the background
I'm looking for a tip to access to the object's properties in the background.
Indeed, with a mousehover, I want to reveal the properties of layer ze.json (the geographical unit).
However, my proportionnal circles hide this layer.
I have not really idea of the procedure envisaged because :
- Circle proportional must be on the top
- Opacity doesn't solve the problem
Maybe I should report the information on proportional circles. But how could I transfer this information ? (not only the population but also the ZE name)
Proportionnal Circles
let rMax = d3.max(featureCollectionZe.features,(d)=>{return d.properties.pop;});
let propCircle = g.attr("class","prop_circle")
.selectAll(".prop_circle")
.data(featureCollectionZe.features)
.enter()
.append("circle")
.attr("transform", (d)=>{return "translate(" + path.centroid(d) + ")";})
.attr("r",(d)=>{return(Math.sqrt(d.properties.pop/rMax))*30;})
.attr("fill","#ffa500")
.attr("fill-opacity",0.8)
.attr("stroke-width",1)
Mouse event
svgZe
.on("mouseover",
(e)=>{return document.getElementById("name").innerHTML=e.properties.nom_ze,
document.getElementById("pop").innerHTML=e.properties.pop;}
)
.on("mouseout",
(e)=>{return document.getElementById("name").innerHTML=" ",
document.getElementById("pop").innerHTML=" ";}
)

Thank you for the tip! Indeed,.append("g")has no sense. I had a displacement problem when I click+move the map with the mouse (latency) but seems disappeared now.

I am not sure, that this solves your problem completely, but have you tried to apply pointer-events: none CSS property to circles?
