[Fixed]-What is a better option to use django-highcharts package to render charts in template or regular ugly rendering in django?

I would suggest normal rendering from front end only as shown in highcharts documentations.

Try to keep backend and front end separate as much as possible. Of course there is a third-party package that you can use but keeping your code modular and segregated is also important.

In future if there is a front end guy who changes/manages the chart code, He need not be forced to learn django first to do front end related tasks. 🙂
