title: GeoJson World Database
body: <p>I am working on a project where it is necessary to display maps of countries and cities using d3.js.</p>
  
  <p>Actually, D3 supports GeoJson format. Usually, I guess, GeoJson format is converted from some other format.</p>
  
  <p>I found some places with this GeoJson data:</p>
  
  <p><a href="http://mbostock.github.com/protovis/ex/countries.js" rel="noreferrer">http://mbostock.github.com/protovis/ex/countries.js</a></p>
  
  <p>But, this is only a list of countries, I am looking for some service or program that gives me the ability to set an ID, get this format, and convert it to GeoJson, or get it in GeoJson better.</p>
  
  <p>Thanks!!</p>
