    <p>I realized that what you want to do is to just reload all the data so here is what I 've done in this <a href="http://jsfiddle.net/agalazis/xLrsb/16/" rel="nofollow">fiddle</a></p> <ul> <li>I have put the d3.json in another function so that I can call it whenever I want to.</li> </ul> <p>Now whenever I want other data:</p> <ul> <li>I use <code>d3.select('svg').remove();</code> in order to remove the original svg</li> <li>I call the function that includes the d3.json to visualise the new data</li> </ul> <p><strong>EDIT</strong></p> <p>For doing it in intervals you can use set timeout as per <a href="http://jsfiddle.net/agalazis/xLrsb/14/" rel="nofollow">my example fiddle here</a>: Your function the function that includes the d3.json code can recursively call it self in this manner:</p> <pre><code> T =setTimeout(function(){ d3.select('svg').remove(); testing(["http://csmonk.com/data1.php","http://csmonk.com/data2.php"], ++count); },2000); </code></pre> <p>to clarify in your case you will do:</p> <pre><code> var T;// (globally) </code></pre> <p>in your &lt;myd3jsonfunctionhere&gt; function add:</p> <pre><code> T =setTimeout(function() { d3.select('svg').remove();&lt;myd3jsonfunctionhere&gt;; },&lt;myintervalhereinms&gt;); </code></pre> <p><strong>More efficient(Best choice in my opinion):</strong></p> <pre><code> window.setInterval(function(){d3.select('svg').remove();&lt;yourd3.jsonfunctionhere&gt;},&lt;intervalinmilliseconds&gt;); </code></pre> <p><strong><a href="http://jsfiddle.net/xLrsb/13/" rel="nofollow">Fiddle</a></strong></p> <p>for the last example your code should be something like:</p> <pre><code>&lt;/script&gt; var w = 1200, h = 900, radius = d3.scale.log().domain([0,312000 ]) .range([ "10", "50" ]);

    2. COcan you tell me one thing that in this example you have used a .php file to load data firstly and then d3.select('svg').remove(); to load another svg write?so when i put a servlet in the place of d3.json() as i used in this question then where should i put this remove thing?i.e you have use link from an external source

    3. COI have done it by interchanging the links but your servlet might serve different data as the time passes so you may be calling the same link in intervals

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.
