If a frontend library needs a to parse JSON, you can use the json
library to convert a python dict to a JSON valid string. Use the escapejs
filter
import json
def foo(request):
json_string = json.dumps(<time_series>)
render(request, "foo.html", {'time_series_json_string': json_string})
<script>
var jsonObject = JSON.parse('{{ time_series_json_string | escapejs }}');
</script>
