Marmelab ArchitectureTree

ArchitectureTree is a single page application to visualize and edit architecture schemas in the browser, built with d3.js and AngularJS.

Sample Visualization

Check out the online demo.


We generally use a client software to draw our system architecture schema, like Microsoft Visio © for example. But often, only one member of the team has this software installed on their laptop. Besides, the schema often uses a specific file format, and there is no standard way to draw the schema. It quickly becomes very hard to maintain the schema as the software evolves.

ArchitectureTree give you the possibility to visualize and edit an architecture schema in your browser, and to save it as a JSON file.


Get The Code

git clone [email protected]:marmelab/ArchitectureTree.git
cd ArchitectureTree

Create Architecture File

Create a JSON description of your system, and save it as

. A good starting point is the provided
example file:
cp data.json-dist data.json

Start Static Webserver

ArchitectureTree is entirely client-side. However, as it uses AJAX to load the architecture file, you'll need a static web server to use it from localhost.

For example, by using the

php -S localhost:4000

Or the

python -m SimpleHTTPServer 4000

Then, navigate to http://localhost:4000/.

Tip: If you commit the code to the

branch of a GitHub repository, it'll be available for viewing.


Filters on

are avalaible on the left hand side of the screen.

Details about a node reveal on the right hand side of the screen when hovering a node.

You can edit the node by clicking on it: the details box turns into a form. After you save your modifications, the JSON in the bottom textarea is automaticaly updated. Note that you can also edit the JSON directly in the textarea.

Since there is no server-side, you have to manualy report the json modifications into the

file, and commit it.

Data description file


file describes your architecture in a json format. It allows versionning by using
or another SCM. It can be edited by anyone with access to the repository.

After any update to the description file, check that it works locally before committing (any JSON validation error will result in a blank screen). All charts rely on this data file.


Each element of your system is defined by a JSON node entry. Here is an example:

    "name": "News",
    "children": [
        { "name": "World" },
        { "name": "Sport" }
    "url": "*",
    "dependsOn": ["Content API", "Xiti", "Search API", "OAS", "Account API", "    Picture API", "Router API"],    
    "technos": ["PHP", "Javascript", "Silex", "NGINX", "Varnish"],  
    "satisfaction": 0.9,
    "host": { "Amazon": ["fo-1", "fo-2"] }


  • name
    : name of the application / service / container
  • children
    : list of sub-applications.
  • url
    : where the application is available (if any)
  • dependsOn
    : list of application dependencies. The mapping is done on the node
    (that means that two nodes cannot have the same name)
  • technos
    : list of technologies used by the application
  • satisfaction
    : Overall quality of the application; it's a number between
    • 1
      for a good application
    • 0.8
      for application which need some refactoring
    • 0.2
      for a bad or not finished application
    • 0
      for an horrible one or not yet started
  • host
    : list of hosts where the application is hosted, grouped by name, with the list of corresponding server names or
    if unknow (eg.:
    { "Amazon": ["front-1", "front-2"] }
    "OVH": ["?"]
