Step 4
(1) Node with max degree: a tree.
(2) Location of a tree: [Center of the canvas].
(3) Location of A black cat: [On the tree, towards the upper part of the tree].
Location of hanging lantern (1-8): Distributed around the upper and side areas of the tree.

Step 5

A tree, General Objects: [0.300, 0.100, 0.700, 0.900] - The tree is central in the image, spanning vertically.
hanging lantern (1), General Objects: [0.200, 0.150, 0.250, 0.200]
hanging lantern (2), General Objects: [0.260, 0.160, 0.310, 0.210]
hanging lantern (3), General Objects: [0.320, 0.170, 0.370, 0.220]
hanging lantern (4), General Objects: [0.380, 0.180, 0.430, 0.230]
hanging lantern (5), General Objects: [0.440, 0.190, 0.490, 0.240]
hanging lantern (6), General Objects: [0.500, 0.200, 0.550, 0.250]
hanging lantern (7), General Objects: [0.560, 0.210, 0.610, 0.260]
hanging lantern (8), General Objects: [0.620, 0.220, 0.670, 0.270] - The lanterns are distributed around the upper and side areas of the tree.
