How can I present this online? Joomla extension?

I have an excel sheet with following columns.
Country
Company
Company location
web address

The first column Country, are the countries that are supported by
the Company field.
The Company, Company location and webaddress are linked.

So one country is serviced by one company, but one company can service
many countries. My questions is how I can present this in a neat way.

My idea was to find some kind of joomla extension that would show a map with interactive colours or something. Maybe a table with the companies and when you mouse over, the countries in the map would light. Or Some other way, something different and nice.
