      <p> In this window graph data from files or the standard output of programs can be read in.
The data has to be in one of the two <a href="technical.html#formats">formats</a> that CaGe
understands.
</p>
      <p><br>

When reading graph data representing plane graphs of very different nature, finding
<em> good </em> 2D and 3D embediings efficiently is especially difficult and the assistance
of the user is asked.
The user can keep embedding information contained in the data or
take that information as a starting point for further refinement.<br>

The embedding programs in CaGe are specialized on certain kinds of graphs, so if a new
embedding must be computed, the user
has to describe which shape he would expect the graphs to have in order to give a hint
which embedder should best be used. The user has to choose whether the expected threedimensional shape is


	  <ul>
		<li>rather flat </li>
		<li>rather spherical  </li>
		<li>rather tubular </li>
	  </ul>

</p>
<p>
Furthermore the user can increase or decrease the number of steps of the embedding routine.
