Not able to find this data/d3tree_data.json file in decision tree visualisation in
dtvis/index.html??

Error : data is null

Decision path table sort only works for paths that are as long as the longest path. It should work for paths of arbitrary lengths.

• Add requirements file
• Raise a custom error if brewer2mpl is not found, alerting the user that they should install the package if they would like to use the default colors, otherwise they can specify their own colors.

Decision paths signs work correctly only for full binary trees

The first column in the decision tree always shows lower or equal sign even if it is the greater than branch. The higher order branches switch signs as they should.

Depending on the security settings of the browser, external data file may not be imported when trying to open the decision tree html file in a Jupyter Notebook cell as an iframe. A simple solution would be to build an index.html template where the data gets directly coded in rather than read in from an external json.

ensure that decision paths search works alphabetically
Increase the size of the decision path table, if the table is too small, long lines can get chopped.

Sklearn decision trees are stored as preorder DFSs, a D3 tree needs rather a hierarchical structure

Bar charts work for leaf nodes but not really for internal ones, currently when bar chart data is loaded, it does not know if it is a leaf node or not so we cannot give a different position depending on it. Either allow bar charts only for leaf nodes or pass whether the node has children in leaftable, e.g., by including a hasChildren switch.

Currently, mouseover brings up a crosstab of class x true/false, however, if the decision tree has a balanced weighting scheme, the sample sizes will show the weighted (balanced) sample size instead of the real one. In this case, it would make much more sense to show percentages of sample size instead of sample size.

Add leaf node labels to the rectangles when the selected plot type is 'no-bar'
