The Crime Data Explorer is like a portal that gives you access to the UCR data sets, such as the Massachusets's data set shown below. The data is obtained using a Data Building Tool. Follow the [AllDownloads] link to get to the Data Building Tool.
To demonstrate how useful this Data is, the webpage (interactively) lets you select a state and select a span of years, The webpage then writes and displays a sample report(*) made from the data determined by your selections. (Massachusetts Crime Rates 2008-2018 Report, p1, p2, p3)(.png*) about the crime rate in Massachusetts during the years 2008-2018. (*Here, each page is just shown as a png image.)
Here is a link to the site directly (not a .png image).

Shortly, we will construct such a report ourselves. This might be where there data came from (used to produce their report).
To get data like that, scroll down to get to the [All Downloads] button (a link).
Follow that link to get to the UCR Data building Tool.
(Opens in TAB)
Use the [UCR Data building Tool] to obtain your data.

Still using their data, can we reproduce this?
A typical data set from these two sites appears to look like this example.
Key point, the data sets appear to stop at 2014.
Can we get a data set that goes beyond 2014?

UCR is the old data Tool and NIBRS is the new data Tool,
as I understand it at the moment. (It is easy to go in circles.)
NIBRS, the new Tool is ucr.fbi.gov/nibrs/2018 (TAB), and some subTools

EPA - Automotive Trends (Opens in TAB)
As another example, at the top of the EPA - Landing Page there is [Environment] with many different links.
I landed at Automotive Trends where I saw these two pictures as well as this image of some trends.

Goal: To be able to obtain and use the EPA's data sets to reproduce their pictures, and hence (in a small way) their analysis. As a follow up Goal: to try to say some more (and more on that else where). (Drag the corner to get a bigger image (IE may not, Firefox should).)
Step 1. Get the data from the EPA site used to make those pictures.
Oh, I did that. Let me show you the link....
Plus a few more promising links....
