How to plot points(data) in D3 using country if i don't have Lat long

Am using d3.js in my angular7 project to display the map and am using https://datamaps.github.io/ datamaps which is also using d3.js. to plot points(data) we need lat-long but what if I don't have lat-long and I have a country name then how can I plot the points(data) without lat-long.

bubble_map.bubbles([ { radius: 10, centered: 'BRA', country: 'USA', data: { Open: 120, Closed: 40, Agriculture: 60, Water: 34, Finance: 10, Transportation: 8, Other: 4, } }, { radius: 8, country: 'USA', centered: 'USA', data: { Open: 120, Closed: 40, Agriculture: 60, Water: 34, Finance: 10, Transportation: 8, Other: 4, } }, { radius: 12, country: 'USSR', latitude: 73.482, longitude: 54.5854, data: { Open: 120, Closed: 40, Agriculture: 60, Water: 34, Finance: 10, Transportation: 8, Other: 4, } } ]}
