I would recommend you to copy the quiz using this function .The quiz does not use svg's at all!, instead it uses CSS and simple images. When you copy the quiz, in the description you will see the CSS code. You can modify the speed of the animation by changing the value of the slide (it is currently set to 10s). Then you should procced to Step 4 - Design Grid. There you shall find the images in the box underneath the header. You should copy the text code from the box and paste it in notepad(or any other text editor). There you should replace the images of country shapes with whatever you wish to use. You can also individually change the size of each image.
