Course Introduction：D3.js Data Visualization: The Magical Use of Data Binding D3.js has become a powerful data visualization library with its declarative programming style, but its learning curve is quite challenging for beginners. This article will explain the core concepts in D3.js - Data Binding or Data Joins - in an easy-to-understand way to help you get started easily. The data binding process is like growing vegetables: Select a plot (SVG): First, you need to select the area to draw the visualization, just like choosing a vegetable field. Digging (selectAll): The selectAll() function is similar to digging a pit. It creates a container for subsequently added elements.

Course Introduction：Go is a new language, a concurrent, garbage-collected, fast-compiled language. It can compile a large Go program in a few seconds on a single computer. Go provides a model for software construction that makes dependency analysis easier and avoids most C-style include files and library headers. Go is a statically typed language, and its type system has no hierarchy. Therefore users do not need to spend time defining relationships between types, which feels more lightweight than typical object-oriented languages. Go is a completely garbage-collected language and provides basic support for concurrent execution and communication. By its design, Go is intended to provide a method for constructing system software on multi-core machines.
