Find distance between nodes

Hi i have a dataset of 1853 rows and 2 columns, sample of dataset is as follows:

 1  105
1  104
2  1100
10  1165
813  1320
15  105
19  90
105  813

i want to create a graph to find distance between each node from other. For example if i enter input node 1, it will show that distance between 1 and 105 is 1, and between 1 and 813 is 2 (because it will come next to 105). and between 1 and 1320 is 3. (as shown in image below). and similarly for other nodes.

Any help will be greatly appreciated.

To calculate just the distances, use https://www.mathworks.com/help/matlab/ref/graph.distances.html

To get the tree of distances from a node like you show, see https://www.mathworks.com/help/matlab/ref/graph.shortestpathtree.html

Thanks for your help. I have one more question. I want to know that how can I do it directly from the dataset i mean without plotting a graph first?

[Walter Roberson]

The routines I referred to do not require drawing anything. You use graph() or digraph() to create the data structures but you do not need to draw if you don't want to.
