%% Display 'darkwater' on Geographic Bubble Charts
% To display 'darkwater' on a geographic bubble chart, call geobubble using the 'Basemap' name-value pair.

tsunamis = readtable('tsunamis.xlsx');
geobubble(tsunamis,'Latitude','Longitude','Basemap','darkwater')

% Alternatively, you can specify the basemap by using geobasemap.

counties = readtable('counties.xlsx');
geobubble(counties,'Latitude','Longitude')
geobasemap darkwater
