How is the bar generated in the webpage?

I want to generate chart reports inside a webpage. But I don't know what technology should I use.
Here is a Chinese website, inside we can see a Flash Graph is included. From the html source code, I can't find any clue for the related technology.

Could you please help?

Thanks a lot.

Hi Jimmy, example you have mentioned here is using adobe, you can use anything from as simple as your java script or excel bar graphs.
It could even be something like reporting charts(different technologies JFreechart or bert or java fx).

See what suits you need.

I've been using HighCharts for a recent project. It may provide what you need.
