    <p>I've actually got a few questions about this tree but I'll ask them separately.</p> <p>I've got a tree (<a href="http://jsbin.com/okUxAvE/1/edit?js,output" rel="nofollow">demo/code</a>), which is obviously a stock d3 horizontal tree for the most part, save for a little tooltip I'm attaching to child nodes.</p> <p>The question is, how can I have the tree expand from the top left of the container instead of radiating out from the middle of the y-axis? In other words, I want to end up with this:</p> <pre><code>START-----Parent 1-----Child 1 \ `---Child 2 </code></pre> <p>etc., where START is at the top left of the SVG container. Note: the child nodes should thus expand downward and to the right.</p> <p>I've been studying how x and y are working here but I just can't seem to figure out how to change this.</p>

    2. COYes; isn't that the same type of thing as my example? It still starts at the center of the y-axis.

    3. COOh right, sorry, misunderstood what you're trying to do. I suppose you could simply take the y coordinate of your root node and subtract half the height as a constant offset.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
