javascript - How to create this picture?

Of course it’s impossible to do this troublesome thing, and you don’t need so many lines, just one:

For example
{
1:888,
2:777,
3:666,
4:999
...
}

What technology is used to generate these line graphs and statistical graphs?

php? JavaScript? Or something else?
What function do you use?
