Analyzing data from my Pi-hole

Hello. My name is Bret, and I am new here. Looking forward to contributing and participating.

Recently downloaded ninety one days worth of DNS queries from my Pi-hole. Which ended up being 1.3 million records, or a one hundred and fifty megabyte CSV file.

To better understand the data, I am experimenting with various visualizations using Python and D3. Resulting in graphs, such as the one below. Which is a streamgraph featuring the number of times I have pinged one hundred particular domains during that period of time.

Has anyone else done something like this? Or, are there any resources for better understanding the DNS query data I am now exploring?

Thank you for the tool. I am glad to be a member of this community.
