This chapter discusses the events that are commonly used in mechanics diagrams, and then makes improvements to the "Advanced-Chapter 2.0" figure diagram, enabling the user to fix the dragged object.In "Getting Started-chapter 9.2" and "Advanced-Chapter 2.0", the following code is used:Force.on ("tick", function () {});The force here is the layout defined in the previous code, and the tick indicates when the motion is in progress every time a frame is

The contents of the data are: some of the provinces contained in China, some of the cities included in the provinces. We say that the data file is written in a JSON file and

the mechanics diagram, for example does not know each vertex draws in which coordinates and so on. So we need to first use layout to transform the data, as we said, the layout in D3 is used to transform the data. The layout of force is:var force = D3.layout.force (). nodes (nodes). Links (edges). Size ([Width,height]). linkdistance ([-100]). Start ();In the code

There are many parameters in the layout of the mechanics diagram, and this article will describe them individually.The Mechanics diagram layout in D3 is calculated using the Verlay integral method, which is a numerical method for solving Newton's motion equations and is widely used in molecular dynamics simulations and video games. The code that defines the layou

D3 is a visual library of JavaScript, you can make a very beautiful table, which has a very interesting mechanics diagram, can be easily dragged, etc., but on the update of the operation of the online introduction of the few, the following describes the mechanics of the update, first look at an example (http:// example.codeboy.me/d3/force-layout.html, click the f

What is the minimum tree chart? I believe that if you will come to see this article, presumably should also have some knowledge of the minimum spanning tree, the minimum spanning tree is the least weight of a spanning tree of the non-graph. Our smallest tree

is the stretching tree. Each time the stretching tree is manipulated, it rotates the accessed node to the root location by means of a rotation. In order to rotate the currently accessed node to the root, we usually rotate the node from the bottom up until the node becomes the root of the tree. The neat thing about "rotation" is that all the basic operations are
