Due to security measures, web browsers impose restrictions on reading local files & cross-origin requests. To work around this, one effective approach is to serve your JSON file from a local web server or utilize a CORS-enabled JSON hosting service like npoint.io. By doing so, you enable your web application to fetch data seamlessly without encountering the cross-origin limitations. Please take a look at this JSFiddle for an example of the same.
