Using iframe in wordpress

Hi – I’m in love with a timeline tool, but i can’t figure out how to embed it into my site.
The provided wordpress embedding plugin is not up to date, and as an alternative it says that you can embed it via iframe. How do i do that, and wich iframe plugin should i use? – Yeah, this may be very simple but i need some easy instructions here!

The timeline i’m talking about

The embed code it gives me:

<iframe src='http://embed.verite.co/timeline/?source=0Agl_Dv6iEbDadHdKcHlHcTB5bzhvbF9iTWwyMmJHdkE&font=Bevan-PotanoSans&maptype=toner&width=600&height=600' width='600' height='600' frameborder='0'></iframe>

The site i want it embedded into

And finally an example of the timeline here

Thanks in advance!
