\section{Assumptions}
The following assumptions are made for the implementation of the node placement algorithm:
\begin{itemize}
    \item There are no hyperedges.
    \item There are no port constraints.
    \item There are no labels.
    \item There are no cross-hierarchy edges.
\end{itemize}

\section{Input File Format}\label{sec:inputFileFormat}
The input to \appname is a JSON file.
An example is displayed in figure~\ref{fig:json-example}.
The structure is as follows:
\begin{itemize}
    \item The object in the JSON file is a node.
    \item A node has the attributes that are displayed in table~\ref{table:node-attributes}. \TODO{remove x and y from implementation}
    \item An edge has the attributes that are displayed in table~\ref{table:edge-attributes}.
\end{itemize}

    name & string & yes & If not omitted, this must be unique for a given parent node. \\\hline
    width & integer & yes & The minimum width of the node.
    The node can be wider if it contains other nodes that need more space. \\\hline
    height & integer & yes & The minimum height of the node.
    The node can be higher if it contains other nodes that need more space. \\\hline
    layers & list of lists of nodes & yes & The layers of nodes inside this node (Hierarchy). \\\hline
    edges & list of edges & yes & The edges between nodes whose parent node is this node. \\\hline
