Used to include the relationship with the included, also represents the weight of the individual objects, pass often use a round set of a circle to denote the former, with the size of the circle to indicate the latter.First look at the data used in this section: City2.jsonThis is the data for each city's affiliation. We are now going to use the layout of

This demand is actually quite clear, but the online search out of the tutorial is a mess, feel really need to summarize their own.D3.js is now widely used in data visualization, and with the continued development of big data, the framework is expected to become more prevalent in the future (it is said that its author Mike Bostock began full-time development, previously in charge of the New York Times data visualization engineer, he himself moved from New York to San Francisco ...). ）。 Follow the

Objective I have already shared with you the two basic graphs of how to use histogram and line charts. Both charts have axes, and now a chart without axes--pie charts. Pie chart Implementation As before, we first put together a simple drawing frame and added an SVG canvas. But notice here that, for the sake of the arcs on the Gao diagram, we move the G element that combines these elements to the center of the canvas: Simulate data and transform To Gao graphs, we simulate some o

The following uses angular direve VE and json data in the D3 with the donut chart label: angularjson Use angular resource to load json data in priorityData. json and D3 to draw a donut chart. Run index.html: The json data in priorityData. json is as follows: { "priority":{ "Blocker":12, "Critical":18, "Major":5, "Minor":30, "Trivial":24 }} The index.html code is as follow

It is not difficult for d3.js to draw a vector chart. it is difficult to drag and drop it. In fact, jquery and easyui both provide the draggable drag and drop method, you only need to re-draw the line when dragging the drop event of a div. It is not difficult for d3.js to draw a vector chart. it is difficult to drag and drop it. In fact, jquery and easyui both provide the draggable drag and drop method, you

[5.1] a relatively complete chart is created, but it is static. Do you want to make its dynamic effect? In D3, you only need a few lines of code. This section involves the use of four functions. 1. transition () You only need to add this to start the transformation effect. Add it to two States, for example: .attr(fill,red).transition().attr(fill,steelblue) As shown in the preceding code, the colors of fill in the upper and lower attributes are differ

Matplotlib can be used to create very beautiful and precise mathematical graphs:But sometimes it's time to exchange ideas. Do not want to be so rigorous formal, want to use that kind of relaxed, graffiti-style graphics:The MATLAB xkcdify project can be used to generate the above graffiti works:Https://github.com/slayton/matlab-xkcdifyJust this article will introduce the use of JavaScript D3 library to generate your own graffiti online. This is much mo

Using D3,JS to visualize data, you can separate the data from the code and make it easier to modify the data later.This time using D3.js to draw a five-D radar chart that will compare the five properties of multiple objects on a single graph.The data is written to the Data.csv, and the data type is written to the Type.csv file.The effect is as shownSource Connection: http://download.csdn.net/detail/svap1/73

number of bound data. The following usually operates first with append.3. Exit () when the corresponding element is too large (the number of bound data When the corresponding element is too large, it is usually necessary to delete the element so that it is equal to the number of bound data. The back is usually followed by the remove operation.Here's a look at the specific usage:The above code uses the variable name update and enter respectively to represent the respective part, the result of th

In the previous section we learned how to rotate x-axis labels and custom label content, and in this section we will touch Animations (transition)First, we're going to add a button to the page that calls our animations when we click on this button. So, we also need to add two things on the original basis.Add a button"option" >"UpdateButton" type="button" value="Update" onclick="UpdateData ()"/> Add an animation functionfunction UpdateData () { Get the data again

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 e

When I first approached the use of D3.js, one of the most confusing places was data (), enter (), and exit () . After I have been in touch for a while and have some understanding, simply say what I understand.data ()Let's look at an example: Body > P > P > P > P > P > P > Body >Execute code:D3.select ("Body"). SelectAll ("P"). data ([1, 2, 3])Here, Data() is used to bind to the selected DOM element . After that, you can do something abou

In D3.js, there are two functions for selecting an element: Select and SelectAll. Let's start by explaining their differences: Select is the first selection of all specified elements SelectAll is the selection of all of the specified elements (for later simultaneous operation) To see a specific example, the following code is available:[HTML]View PlainCopy html> head> meta charset="Utf-8"> title>select,append,exittitl

Then the previous one discussed how to select elements and use data.Now there are three lines of text in the page, the code is:[HTML]View PlainCopy p>hello World 1P> p>hello World 2P> p>hello World 3P> Define a set set with three elements:[HTML]View PlainCopy var set = [' I like dog ', ' I like cat ', ' I like Snake ']; To assign these three strings to the three [HTML]View PlainCopy var sp = d3
