I want to make a dashboard in dashboard studio which in middle there will be a world map and it will be surrounded by small panels. is it possible if yes then can you provide json code for that
On your Splunk Search Head, you can find some examples for this.
Example Link - change your server name to
https://MY_SPLUNK_SERVER/en-GB/app/splunk-dashboard-studio/example-hub-security-summary-dashboard
Or you can go to search > dashboards>visit examples hub - there are plenty of examples there for you to check and see the json code.
