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.
enter image description here

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="&nbsp",

        document.getElementById("pop").innerHTML="&nbsp";}

    )

side notes: zoom can be shortened by g.attr("transform", d3.event.transform); , what is that purpose of the last .append("g"); , make the stroke of the .ze. more explicit in the style, it is now due to render artefacts that you see the edges

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?
