Hello @saurav77,
you could use websockets to do this. Websockets are easily integrated with Laravel Echo. https://laracasts.com/series/get-real-with-laravel-echo
https://github.com/laravel/echo
https://beyondco.de/docs/laravel-websockets/getting-started/introduction
Alternativly you could just use polling https://freek.dev/1036-long-poll-requests-with-laravel.
js Example https://gist.github.com/twmbx/2321921670c7e95f6fad164fbdf3170e
The diffrence is: Websockets have a continuous connection to your server. You could update the chart exactly when the data changed. This would be the real real-time experience.
Polling just sends an requests every few seconds to retrieve the data you need. The chart would just be updated every few seconds (or every second, depends on your settings) :D
