Number of companies per address in Slovenian towns
A map (in Slovenian language) showing addresses with more than five registered companies in main Slovenian towns. Inspired by questionable business practice of chain ownership - setting up a chain of companies, each one owned by previous one, to transfer funds and labor between then and avoid paying salaries and benefits in the process.
The map doesn't show only suspicious companies. There is no way of isolating them using open source data, one must be a government inspector for that. But it's an attempt to make an exploratory software to help with that task, as the data for each address shows list of companies and a chart of business categories associated with them.
