And you can extend it with advanced selection techniques, such as a Voronoi overlay or a closest-target search:īest of all, the drag behavior automatically unifies mouse and touch input, and avoids browser idiosyncrasies. The drag behavior can be combined with other behaviors, such as d3-zoom for zooming. For example, you can use it to lasso elements in a scatterplot, or to paint lines on a canvas: But the drag behavior isn’t just for moving elements around there are a variety of ways to respond to a drag gesture. You can also use d3-drag to implement custom user interface elements, such as a slider. For example, you can use d3-drag to facilitate interaction with a force-directed graph, or a simulation of colliding circles: D3’s drag behavior provides a convenient but flexible abstraction for enabling drag-and-drop interaction on selections. ![]() Drag-and-drop is a popular and easy-to-learn pointing gesture: move the pointer to an object, press and hold to grab it, “drag” the object to a new location, and release to “drop”. ![]()
