1. A computer-implemented method for presenting a hierarchical data structure in a first grid, the method comprising: receiving the hierarchical data structure, the hierarchical data structure including a plurality of nodes each including a node content type identifier, the plurality of nodes comprising: a first node with a first node content type identifier value, a second leaf node, which is a child node of the first node, with a second node content type identifier value, a third leaf node, which is a child node of the first node, with a third node content type identifier value, a fourth node, which is a sibling node of the first node, with a fourth node content type identifier value, a fifth leaf node, which is a child node of the fourth node, with the second node content type identifier value, a sixth leaf node, which is a child node of the fourth node, with the third node content type identifier value, a seventh node, which is a parent node of the first and fourth nodes, with a fifth node content type identifier value, an eighth node, which is a sibling of the parent node, with a sixth node content type identifier value, a ninth node, which is a child of the eighth node, with a seventh node content type identifier value, a tenth leaf node, which is a child node of the first node, with the second node content type identifier value, a eleventh leaf node, which is a child node of the first node, with the third node content type identifier value, a twelfth node, which is a child of the eighth node, with an eighth node content type identifier value, a thirteenth leaf node, which is a child node of the fourth node, with the second node content type identifier value, and a fourteenth leaf node, which is a child node of the fourth node, with the third node content type identifier value; populating positions of the first grid, the first grid comprising first, second, and third columns and first, second, and third rows, as follows: at the first column, second row: a value based on the first node content type identifier value, at the first column, third row: a value based on the fourth node content type identifier value, at the second column, first row: a value based on the second node content type identifier value, at the second column, second row: a value based on a value stored in the second leaf node, at the second column, third row: a value based on a value stored in the fifth leaf node, at the third column, first row: a value based on the third node content type identifier value, at the third column, second row: a value based on a value stored in the third leaf node, and at the third column, third row: a value based on a value stored in the sixth leaf node; populating positions of a second grid comprising fourth, fifth, and sixth columns and fourth, fifth, and sixth rows such that the fourth column contains values based on the seventh and eighth node content type identifier values, the fifth column contains a value based on the second node content type identifier value and values based on values stored in the tenth and thirteenth leaf nodes, and the sixth column contains a value based on the third node content type identifier value and values based on values stored in the eleventh and fourteenth leaf nodes; and populating positions of a third grid containing values based on the eighth and ninth content type identifier values and links to the first and second grids, wherein the second node content type identifier value is not the same as the third node content type identifier value; and the first row is positioned above the second and third rows.
