If you need to retrieve some data from your Google Analytics account in Laravel 5, then laravel-analytics is the package for you. Assuming the analytics tracking code is installed on your site, the package allows you to determine which pages are visited the most, which browsers are used most to visit your site, and lots more.

When using it in conjunction with a chart library like chart.js you could make some nice visualisations of the traffic on your website:

The package can also cache the responses of the Google API for a certain amount of time.

In addition to the standard methods to fetch visitors, pageviews, etc for a certain period there is also a method with which you can fire of you own query. Take a look at the core reporting API  to get an idea of what's possible.
