Tooltip not showing up in a chart

I define the tooltip:

var tooltip = d3.select(TARGET_ELEMENT).append("div")

.attr("class", "tooltip")

.style("opacity", 50)

.attr("style", "position: absolute; pointer-events: none; background: lightsteelblue; width:200px; height:28px;");

and then work with it as I have seen in various examples:

 g.selectAll("dot")

        .data(Dataset)

        .enter().append("circle")

        .attr("r", 3)

        .attr("cx", function(d) { return xScale(d.date); })

        .attr("cy", function(d) { return yS(d.value[a]); })

        .on("mouseover", function(d) {

            tooltip.transition()

                 .duration(200)

                 .style("opacity", .9);

            tooltip.html(d["date"] + "<br/> (" +"TEST"+ ")")

                 .style("left", (d3.event.pageX + 5) + "px")

                 .style("top", (d3.event.pageY - 28) + "px");

        })

        .on("mouseout", function(d) {

            tooltip.transition()

                 .duration(500)

                 .style("opacity", 0);

        });

However, nothing is showing up. No errors in the console. I verified that the "mouseover" is invoked correctly but that is it. What is the problem with this code?

I assume that you are using d3 v4/v5. Just change the tooltip to:

var tooltip = d3.select("#target").select(".tooltip").data([0]);

tooltip = tooltip.enter().append("div")

    .attr("class", "tooltip")

    .merge(tooltip)

    .style("opacity", 50)

    .attr("style", "position: absolute; pointer-events: none; background:lightsteelblue; width:200px;height:28px;")

You can learn about d3 general update patter here.

I've also created a simple fiddle for this.
