These concepts were abstract , so we list some examples in the Worker to illustrate them. You can click here  to have a look.

Done.

Please ask a native english person to help correct some of the language, I could guess what it means but was unsure

Hello there，

We've posted a BTS Worker Proposal - Data Visualization：Investigation, Design and Implement, and our main purpose is to "visualize" and to analyze the data on the chain without being entangled in the underlying implementation.

We have published questionnaires using Chinese/English to collect data visualization requirements:
Chinese version : BTS数据可视化需求调查
English version:  An Investigation for BTS Data Visualization Worker Proposal

Thanks for your time. It's our pleasure to have your feedbacks.
