Bundle is a rather peculiar layout in D3, with only two functions, and it needs to be used in conjunction with other layouts. This paper describes how to make the bundle diagram.There are very few examples of bundle graphs, and it is easy to find: http://bl.ocks.org/mbostock/1044242However, this example is somewhat complex, not easy to understand, and there is no corresponding explanatory text (D3 official

First, the chart interactive operationInteraction with a chart means that one or more listeners are set on a graphic element and react accordingly when the event occurs.Interaction, refers to the user has entered some kind of instruction, the program accepts the instruction must make some kind of response. For visual charts, interaction can make a chart more vivid and more expressive. For example, drag some of the graphics in the chart, slide the mouse over the graphic to appear, zoom in or out

If you want to know more about D3.js, welcome to http://www.ourd3js.com/discussion D3 is a javascript class library for Data-Driven Documents. If you do not know what javascript is, learn about javascript first. To put it simply, D3.js is mainly used to operate data. It injects life into your data by using HTML, SVG, and CSS, which is converted into various easy

[D3.js] SVG-Axes (coordinate axis)Axis D3 Axis components are designed for D3 quantitative, time, and ordinal scales. # D3.svg. axis () create a default axis. # The aixs (selection) axis applies to selection or transition. The selector must contain an svg or g element. For example,

categories: vector graphics, text, and reference bitmap. The common examples are as follows: Vector Graphics: SVG, rect, circle, ellipse, path, line ), ploygon, title, DESC, G, and defs ). Text: Text, anchor () Reference bitmap: image (image element) These elements are simple and can be understood simply by reading the document, but I personally think they are worth mentioning as follows: The path function of SVG is powerful, and almost any image can be implemented. Coupled with the loss

First, put the effect map out: With a histogram of the basic elements: column, axis, scale, value and so on. It has to be said that D3.js is more troublesome than the echarts of direct use, but it is more free. Let's see how it's going to happen. Determine the size of the canvas var width = 400; var height = 400; Add an SVG canvas to the body-var svg = D3.select ("Body"). Append ("SVG"). attr ("wi

In a blink of an eye, this introductory series has accumulated more than 22 articles, I think as d3.js this data visualization tool is enough to get started. I believe that as long as you finish this series, you can complete most of the visualization work in the case of query.The earliest v1.0 version of

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 above:

I:FlowchartIntroduction Flowchart is a brand new workflow mode introduced in wf4.0. It provides a good compromise between the sequential and statemachine stream control models. Flowchart allowedYou can use a step-by-step method to implement some simple decision-making and conversion functions, but it also allows you to return previous activities in the workflow. For many users, the

represent the number of peaches in the next day. The algorithm is rewritten as follows: 1) a1 = 1; {1st peach count in 0 days, initial value of A1} I = 9. {Counter initial value is 9} 2) A0 = 2*(A1 + 1 ). {Calculate the number of peaches for the day} 3) a1 = A0. {Use the peach count of the day as the initial value for the next calculation} 4) I = I-1. 5) if I> = 1, go to 2 ). 6) output the A0 value. 2 )~ 5) steps are loops. This is a process from concrete to abstract. The specific method is as

First, we have a background: we have a Activiti workflow system already on-line, the operation of the flowchart has been packaged to deploy, view, delete the interface. At this point the customer proposes to modify the node name in the individual flowchart.My first idea is to modify the flowchart BPMN file locally, then go to the client first call the delete interface to delete the old

The relationship between the selection set and the data is the most important foundation of D3, in the "Getting Started-7th chapter" When a little explanation, for to master good D3 is not enough. Therefore, a new classification is devoted to the relationship between the selection set and the data, including the use and working principles of data binding, the principle of update, enter, exit, and how to use

Data Visualization and D3.jsData Visualization Data visualization is a topic for how to better present data. After the emergence of big data, it becomes more important and urgent. Previously, using excel for column charts, pie charts, and line charts was one of the most commonly used data visualization methods. On the WEB end, the popular extjs, fusioncharts, and jfreechart were used, or the relatively less popular plug-ins such as amchart, highcharts

Since the D3 class library and array are closely related, it is necessary to discuss the data binding in D3 and how to operate inside the array.Arrays in the 1.D3Like other programming languages, D3 array elements can be types such as numbers or characters, such as:SOMEDATA=[20,36,48,59,600,88];In addition, considering the convenience of JSON data in network tran
