To disable double click zoom for d3.behavior.zoom, you can modify the zoom behavior by removing the "dblclick.zoom" event listener. Here's an example:

 1

// Create the zoom behavior
var zoom = d3.behavior.zoom()
    .on("zoom", zoomed)
    .on("dblclick.zoom", null); // Disable double click zoom

// Apply the zoom behavior to an element
d3.select("svg")
    .call(zoom);

// Define the zoomed function
function zoomed() {
    // Handle zoom event here
    console.log("Zoomed!");
}


In this example, we create the zoom behavior with the "d3.behavior.zoom()" method. We then remove the "dblclick.zoom" event listener by setting it to null using the ".on("dblclick.zoom", null)" method.


Finally, we apply the zoom behavior to an SVG element using the ".call(zoom)" method. Now, double-clicking on the SVG element should not trigger the zoom behavior.
