Those trees (except the circular one) were made using iTOL (Interactive Tree Of Life), an online tool for the display, annotation and management of phylogenetic trees.
You can download each tree in the format of your choice.
If you want to display the heatmap, you have to download the dataset file and log in to iTOL.
Then, once the tree is open in iTOL, simply click and drag the dataset file on the tree. For more information, visit the help section.
