Directed Graph Plugin Examples

Howto

HowtoDirectedGraphs has a basic howto on creating directed graphs using dot. The below examples show some of the capabilities of the DirectedGraphPlugin

Examples

Cole's example

You type:

<dot >
digraph G {
    subgraph cluster_c0 {a0 -> a1 -> a2 -> a3}
    subgraph cluster_c1 {
        b0 -> b1 -> b2 -> b3;
        label="Group B";
    }
    x -> a0 [style=dotted];
    x -> b0;
    a1 -> a3 [style=bold, label="a1 to a3"];
    a3 -> a0;
    a0 [shape=box, fontname=Courier, fontsize=11];
    a1 [color=red];
    a3 [label="Label\nfor a3"];
    label="Cole's Example";
}
</dot> 

You get: (simulated)

You get: (if installed) digraph G { subgraph cluster_c0 {a0 → a1 → a2 → a3} subgraph cluster_c1 { b0 → b1 → b2 → b3; label="Group B"; } x → a0 [style=dotted]; x → b0; a1 → a3 [style=bold, label="a1 to a3"]; a3 → a0; a0 [shape=box, fontname=Courier, fontsize=11]; a1 [color=red]; a3 [label="Label\nfor a3"]; label="Cole's Example"; }

Clientside imagemap (clickable nodes and edges)

You type:

<dot map="1" size="auto" antialias="on">
digraph G {
    URL="http://foswiki.org";
    Plugins [URL="http://foswiki.org/Extensions"];
    DirectedGraphPlugin [URL="http://foswiki.org/Extensions/DirectedGraphPlugin"];
    Plugins -> DirectedGraphPlugin;
}
</dot>

You get: (simulated)

You get: (if installed) digraph G { URL="http://www.foswiki.org"; Plugins [URL="http://foswiki.org/Extensions/PluginPackage"]; DirectedGraphPlugin [URL="http://foswiki.org/Extensions/DirectedGraphPlugin"]; Plugins → DirectedGraphPlugin; }

You get: (simulated, antialiasing on)

You get: (if installed, antialiasing on) digraph G { URL="http://www.foswiki.org"; Plugins [URL="http://foswiki.org/Extensions/PluginPackage"]; DirectedGraphPlugin [URL="http://foswiki.org/Extensions/DirectedGraphPlugin"]; Plugins → DirectedGraphPlugin; }

Usecase description / state diagram

To view the dot input for this example, click the [dot] link located below the diagram.

You get: (simulated)

You get: (if installed) digraph G { size="9"; graph [rankdir="TB" label="1st Time Use/Phone Registration" fontsize=12 bgcolor="#eeeeff"]; node [shape=box fontsize=9]; edge [color=blue fontsize=8 font="Arial"]; cell_number_entry [label="Cell Number Entry"]; welcome [label="Welcome Page"]; member_name_creation [label="Member Name Creation"]; password_creation [label="Password Creation"]; member_name_unavailable [label="Member Name Unavailable"]; email_entry [label="Email Entry"]; zip_code_entry [label="Zip Code Entry"]; tos [label="TOS"]; decline_confirmation [label="Decline Confirmation"]; registration_confirmation [label="Registration Confirmation"]; member_name_entry [label="Member Name Entry"]; password_entry [label="Password Entry"]; confirm_phone_number [label="Confirm Phone Number"]; unsuccessfull_sign_in [label="Unsuccessfull Sign In"]; email_confirmation [label="Email Confirmation"]; main_menu [label="Main Menu"]; initial_screen [label="Initial Screen"]; exit_application [label="Exit the Application"]; welcome → initial_screen [label="First Time"] initial_screen → member_name_creation [label="Register"]; initial_screen → member_name_entry [label="Sign In"]; member_name_creation → password_creation [label="Valid Member Name" dir="both"]; member_name_creation → member_name_unavailable [label="Invalid Member Name" dir="both"]; welcome → password_creation; password_creation → cell_number_entry [dir="both"]; member_name_entry → password_entry [dir="both"]; cell_number_entry → email_entry [dir="both"]; password_entry → confirm_phone_number [label="Auth. Successful" dir="both"]; password_entry → unsuccessfull_sign_in [label="Auth. Unsuccessful"]; email_entry → zip_code_entry [dir="both"]; zip_code_entry → tos [dir="both"]; confirm_phone_number → main_menu; unsuccessfull_sign_in → member_name_entry [label="Try Again" constraint="false"]; unsuccessfull_sign_in → email_confirmation; tos → decline_confirmation [label="Decline" dir="both"]; tos → registration_confirmation [label="Accept"]; decline_confirmation → exit_application [label="Yes"]; registration_confirmation → main_menu [label="10 Sec/NEXT"]; }

Component architecture (inline SVG)

This is a typical example of a component architecture drawing (This kind of graph is also easy to do in Foswiki:Extensions.JHotDrawPlugin if you like the look but you prefer to draw it manually using your mouse).

Click the [dot] link located below the diagram to view the input. Note that this example is an inline SVG with fallback to PNG

You get: (simulated)

You get: (if installed) digraph G { graph [rankdir=LR, size="9.5,2.5"] subgraph cluster_0 { graph [label=User] edge [style=dashed] browser [label="WWW\nbrowser" URL="http://www.mozilla.org/"] svgplugin [label="SVG Plugin" URL="http://www.adobe.com/svg/viewer/install/old.html"] pdfplugin [label="PDF Plugin" URL="http://www.adobe.com/support/downloads/product.jsp?product=10&platform=unix"] svgplugin → browser svgplugin → browser [dir=back] pdfplugin → browser pdfplugin → browser [dir=back] { graph [rank=same] pngpage [label=PNG shape=box URL="/webdot/webdot/demo.dot.dot.png"] svgpage [label=SVGZ shape=box URL="/webdot/webdot/demo.dot.dot.svgz"] pdfpage [label=PDF shape=box URL="/webdot/webdot/demo.dot.dot.pdf"] } pngpage → browser [dir=none style=dotted] svgpage → svgplugin [dir=none style=dotted] pdfpage → pdfplugin [dir=none style=dotted] } subgraph cluster_1 { graph [label="Server 1"] httpd1 [label=httpd URL="http://httpd.apache.org/"] webdot [label="/cgi-bin/webdot" style=filled fillcolor=yellow color=black URL="/webdot/"] } subgraph cluster_2 { graph [label="Server 2"] httpd2 [label=httpd URL="http://httpd.apache.org/"] "demo.dot" [shape=box URL="/webdot/demo.dot"] httpd2 → "demo.dot" [dir=none style=dotted] } browser → httpd1 → webdot → httpd2 browser → httpd1 → webdot → httpd2 [dir=back] }

Simple LAN setup (custom icons / shapefiles)

This type of graph can also easily be extended, for instance making network nodes clickable, pointing to asset databases or similar.

Click the [dot] link below the diagram to view the input.

You get: (simulated)

You get: (if installed) digraph G { size="2,3!"; dpi="100"; edge [arrowhead=none color=blue]; node [fontcolor=blue color=white]; Workstation [shapefile="Sun_Workstation.png"]; Printer [shapefile="Printer.png"]; Internet [shapefile="Cloud-Filled.png"]; Router [shapefile="Wireless_Router.png"]; Switch [shapefile="Workgroup_Switch.png"]; Laptop [shapefile="Laptop.png"]; Workstation → Switch; Printer → Switch; Switch → Router; Router → Internet; Laptop → Router [style=dotted]; }

You get: (if installed, antialiased) digraph G { size="2,3!"; dpi="100"; edge [arrowhead=none color=blue]; node [fontcolor=blue color=white]; Workstation [shapefile="Sun_Workstation.jpg"]; Printer [shapefile="Printer.jpg"]; Internet [shapefile="Cloud-Filled.jpg"]; Router [shapefile="Wireless_Router.jpg"]; Switch [shapefile="Workgroup_Switch.jpg"]; Laptop [shapefile="Laptop.jpg"]; Workstation → Switch; Printer → Switch; Switch → Router; Router → Internet; Laptop → Router [style=dotted]; }
