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-to-understand and beautiful images.
Let's take a look at a simple example.
Now there is a set of data, [4, 32, 15, 16, 42, 25]. Now I want people to see their relationship at a Glance. What should I do? Of course, there is not much data here. A guy with that eye is coming up and saying that I can see it at a glance! However, it is more intuitive to display images, such:
Release/release + CiAgICDPwsPmy7XSu8/release + 1tCw/Lqsz + C52LXEanPOxLz + vLS/ySA8YnI + CiAgICAgPGJyPgogICAgMi67ub/release + release "brus" H: java; "> <script src =" http://d3js.org/d3.v3.min.js "charset =" UTF-8 "> </script> however, the network connection must be valid during use, it cannot be used when the network is disconnected.
Now, you can start your D3 journey.
