3D Plot of a Matrix with only Char data type

1. I have a matrix which with Char data type i.e All data are in text format.
2. My goal is to make an x-y-z plot that will rep these data in an image format
3. Can this be done in Matlab
4. Data sample below

x= 'USA', 'Germany', 'South Africa', 'China', 'Mexico', 'Australia'

y = 'America', 'Europe', 'Africa', 'Asia', 'South America', 'Australia'

z= 'First world', 'Tech', 'Developing', 'Business', 'Work force', 'Medicine'

Could you post an example of what the final result would resemble ?

@Cutie, perhaps take a look at the MATLAB Gallery, and think about which type of plot might be able to translate your type of data into a visualization.

Thank you @Walter Roberson.

Kindly see output from the code below:

x= {'USA',  'Germany', 'South Africa', 'China', 'Mexico', 'Australia'};
y = {'America', 'Europe', 'Africa', 'Asia', 'South America', 'Australia'};
z= {'First world', 'Tech', 'Developing', 'Business', 'Work force', 'Medicine'};

figure
zz = ones(6,6);
zz= 7*zz;
bar3(zz)
xticklabels(x)
yticklabels(y)
zticklabels(z)

The idea is to show how x (countries), y (continent) and z (related/shared characteristics) are integrated in a matrix-like manner. We want to see inter-relationship among them.

x= {'USA',  'Germany', 'South Africa', 'China', 'Mexico', 'Australia'};
y = {'America', 'Europe', 'Africa', 'Asia', 'South America', 'Australia'};
z= {'First world', 'Tech', 'Developing', 'Business', 'Work force', 'Medicine'};

% convert string to categorical (numerical)
xc = categorical(x);
yc = categorical(y);
zc = categorical(z);

% plot the result, eg. stem3
figure
stem3(xc, yc, zc)

@Chunru, thank you so much

1. but how do I show the interconnection between?
2. and how do I convert the final output represent back to the original string/char?
3. Can the output all be of the same hieght? since the aim is to show inter-relationship between them.
