Create an interactive online visualisation of how the London underground has grown

Information for the business: We sell London walking tours, including tours of the tube. We sell most of our tours online
Industry: Business
Design details: I'd like to create a interactive tool that shows how the London tube network has grown over time.

I'd like the first view to be of the modern day tube map, but with most of the lines and stations greyed out. There would be a large date in the corner, which would read '1863'.

The user will be able to move a slider from the right to the left, from 1863 to the present day, to see parts of the modern tube map being turned from grey to filled in.


In terms of the basic concept, you can use this as inspiration (if you have the right plugin) – http://visualization.geblogs.com/visualization/aging/


I will provide you with the timeline you'll need to use, saying years, lines, and sections of track.


Please supply me with the final editable file as part of the fee.


We'll put your interactive graphic onto a page of our website. Please let me know what technology you intend to use so most people can see it on most devices, and which devices will and won't be able to see what you've created.

I'd also like to see some examples of your previous work on interactive graphics.
Target audience: Tube geeks
Ideas for the visual style: Tube map, clean infographic style.
Things to avoid: Clutter and nasty fonts
