How to Merge Multiple SVG Files into a Single Animated SVG?

I have a large number of SVG files that represent frames of a bar chart race animation. I’ve uploaded a sample of these files here:

I want to merge them into a single animated SVG file and set a specific FPS (frames per second) for the animation. Each SVG file should act as one frame in the final animated SVG.

I’ve tried the following tools but couldn’t achieve the desired result:

• https://github.com/astraw/svg_stack
• https://github.com/btel/svg_utils
• https://github.com/DannyBen/victor
• http://www.imagemagick.org/Usage/montage/

What tool or method can accomplish this? Any help would be appreciated!
