I got involved in a data analysis project that needed a website with program genereated diagrams. Quickly after some research, I found echarts from Baidu.com, and D3.js are the most popular diagram plugins currently. Given sometime for my first experiements with these data visualization frameworks, I got some result here, in the end actually I acquired an award from it, lol. There were still lots of work left for this, but I’m glad that I worked it out, especially I’m happy with the Async Programming technique part I learned. Later on I used Ionic, AngularJS and many more, will post these later.
