You can remove tooltips on line when clicking a button in D3.js by selecting the tooltip element and setting its display property to "none" using the style() method. Here is an example code snippet to achieve this:

// Add tooltip to the line
var tooltip = d3.select("body").append("div")
    .attr("class", "tooltip")
    .style("display", "none");

// Define the line
var line = d3.line()
    .x(function(d) { return x(d.date); })
    .y(function(d) { return y(d.value); });

// Add the line to the svg
svg.append("path")
    .data([data])
    .attr("class", "line")
    .attr("d", line);

// Add a button to remove the tooltip
d3.select("button").on("click", function() {
    // Hide the tooltip
    tooltip.style("display", "none");
});


In this code snippet, we first create a tooltip div element and set its style to "display: none". Then, we add a button element and attach a click event listener to it. When the button is clicked, the tooltip is hidden by setting its display property to "none".


You can customize the tooltip style and behavior further based on your requirements.
