Bar Chart Development Tutorials, Guides & Insights

svg.selectAll("rect")
    .data(data)
    .enter()
    .append("rect")
    .attr("x", (d, i) => xScale(i))
    .attr("y", d => yScale(d))
    .attr("width", xScale.bandwidth())
    .attr("height", d => height - yScale(d))
    .attr("fill", "steelblue")
    .on("mouseover", function () {
        d3.select(this).attr("fill", "orange");
    })
    .on("mouseout", function () {
        d3.select(this).attr("fill", "steelblue");
    });

Now, when a user hovers over a bar, it changes color to orange, and reverts back when the mouse is moved away.
