I have loaded some logs onto Kibana through logstash but not able to visualize it. Please help.

When i click on the available field on the left pane, it does not show me any option to visualize. How can I see visualization?
Can't see your image so just guessing.
Did you create an index pattern?
I have pasted the image. Please check now.

When you click on the index names like in the picture above does your index that you saved your data show up?

here's the index patterns. The index that data was saved to is logstash
Please correct me if I am wrong in my understanding.
Ok I think I misunderstood. If you want to visualize trying going to Visualize -> Lens.
If you want to see the data on discover you can click ADD button but that only adds that column of data in the results pane.
What type of visualization do you want to do?
I want something like below:
This above data is indexed through Filebeat. You see how there is an option to visualize the available fields.
I want to have that option when I load the data via logstash.
