What is the best software to use for an interactive, horizontal scrolling website?

I'm looking to create a Social Impact Report for one of our charity projects as a 'walkthrough' interactive scrolling experience, similar to the outstanding report Mailchimp here: https://mailchimp.com/annual-report/

I've looked at Pure CSS examples and am well versed in HTML and CSS, but I'm hoping that there's some software out there that can achieve the same UX without fiddly coding.

Any suggestions gratefully received!
