Wise Home - home assignment

Let's say Wise Home wants to expand globally, and we need an interface to find countries with large population densities and accessible languages. Build a tool to help management decide where to expand:

• Create a new project hosted in a public repo on https://github.com/ (or similar)
• Use the https://restcountries.com/ (v3) API to load countries
• Display results in a table, showing:
  • Flag
  • Country name
• Population density
