Part of the design display: How to make a visual large-screen template?
With the development of artificial intelligence, more and more visualization needs have emerged, and the requirements for visualization are getting higher and higher. Of course, as long as you understand more, visualization is also a very simple thing. Here are some simple references
1. Sort out your needs and see what kind of data needs to be displayed, what dimensions are needed, etc.
2. Research on visualization tools, For example, the simplest one is Excel, the more complex ones include R, Python, etc., and online tools, such as Baidu's Echarts, etc.
3. Have some research on visualization, such as map visualization, Sankey diagram, chord diagram , rose diagrams and other advanced pictures, only if you understand them can you have design ideas. Here are a few for you to check out.
4. Use the visual templates designed by others as a reference, so that it can be used as a better design. I will give you a few references
5. According to the charts and business, evaluate the aesthetics. Weigh it against the degree of business satisfaction. It cannot be too ugly. Of course, you cannot give up the actual response to the business for the sake of beauty.
