    <p>I'm trying to figure out if Backbone.js is the right framework for my current project: a visualization app.</p> <p>I have a number of questions:</p> <p><strong>1) State / Routing?</strong></p> <p>As this is not your typical RESTful app, but rather a visualization application with various chart types and settings for these charts, how do i maintain state in the URL? Let's say my areaChart model has a number of defaults like this:</p> <pre><code>AreaChartModel = Backbone.Model.extend({ defaults: { selectedCountries: [], year: 1970, stacked: false }, initialize: function(){ [...] } }); </code></pre> <p>On an update to the model I'd like to serialize some of these attributes so that I can bookmark the specific state: chartApp.html#!year=1970&amp;stacked=false etc.</p> <p>And vice-versa, when initing the app with this state, how do I "deparam" the url state and set the model? Can I use Backbone's intrinsic routing?</p> <p><strong>2) Controller and coupling?</strong></p> <p>It seems as Backbone has a pretty tight view-model coupling? Is this really how I should bind for example my areaChartView to the model?</p> <pre><code>AreaChartView = Backbone.View.extend({ initialize: function(){ areaChartModel.bind("change:year", this.render); } }); </code></pre> <p>Isn't this normally the role of the controller?</p> <p><strong>3) Continuation: Model vs. Controller?</strong></p> <p>Given this scenario:<img src="https://i.stack.imgur.com/MW1zi.png" alt="enter image description here"></p> <p>A change in the "Sidebar" should trigger a sequence of functions:<br> 1) "New data for the current selection should be loaded"<br> 2) "Based on this data, the scales in the Visualization view should be updated"<br> 3) "The visualization view should be rendered"</p> <p>Where should I place these functions and how can I create an event in the model that I trigger when the state is stable? (i.e. when all the functions have been invoked and it's time to set the view states?)</p>

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.
