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

p.data (persons, function (d) {return d.id;}). Text (function (d) {return d.id + ":" + D.name;});There is only one statement return d.id in the key function. Represents a key using the ID property of an array item. After modifying the contents of the P element with the data of this binding, the result is as follows:As you can see, the results are not arranged in the order of the New Persons Array (6: Zhang San, 9: John Doe, 3: Harry). As shown in binding procedure 1, the order of the bindings d

simplified version of GeoJSON, which can be said to be a GeoJSON child. The author of D3.js thinks GeoJSON is not very good, and it is more admired Topojson format.Topojson compared to GeoJSON, the file size is reduced by 80% because: The boundary line is recorded only once (for example, the junction lines in Guangxi and Guangdong province are recorded only once) Do not use floating-point numbers, use integers only But Topojson seem

How about the Shenzhou Tang one machine? We can learn from the following to understand the Shenzhou Tang M35 d3 Integrated machine configuration content, Shenzhou released the Tang Dynasty in one model for the M35 D3, its configuration performance? Let's get to know each other. Tang-m35 D3 equipped with Intel dual-core processor, the main frequency of 2.1

Online DemoIf you want to create a nice text cloud or tag cloud effect, you can consider using D3-cloud, which is an awesome open source font cloud effect JavaScript class library, based on the well-known d3.js, can help you generate similar wordle.com style fonts or tag cloud effects. This class library uses the HTML5 canvas to generate the font effect, and the entire layout algorithm can be implemented a

Recently to go back to school to do the completion of the set, ready to do a related algorithm, I heard that Python operations better, specifically to learn. Let's start with the basics .......... ........... D31.set elements are not duplicated, no order.
