    <p>(This addresses your original question, described in the title, and doesn't go into the problems installing chart-cairo or chart, etc, which really should be spun out into different questions)....</p> <p>The graphviz package includes some example graphs in module Data.Graph.Inductive.Example that can be used to get you up and running. You can see the list of included graphs at <a href="http://hackage.haskell.org/package/fgl-5.3/docs/Data-Graph-Inductive-Example.html" rel="nofollow noreferrer">http://hackage.haskell.org/package/fgl-5.3/docs/Data-Graph-Inductive-Example.html</a>.... I will use one called <code>clr479</code>.</p> <p>Once you have a graph, you can convert it to an internal structure representing the dot format using <code>graphToDot</code>. Note that you will need to supply some parameters, which are described in <a href="http://hackage.haskell.org/package/graphviz-2999.11.0.0/docs/Data-GraphViz.html" rel="nofollow noreferrer">http://hackage.haskell.org/package/graphviz-2999.11.0.0/docs/Data-GraphViz.html</a>. Just to get up and running, I will use the supplied <code>nonClusteredParams</code>.</p> <pre><code>let graphInDotFormat = graphToDot nonClusteredParams clr479 </code></pre> <p>Then, you will need to convert this to text suitable for input to the <code>dot</code> program. You can do this with <code>renderDot . toDot</code></p> <pre><code>let outputText = renderDot $ toDot graphInDotFormat </code></pre> <p>and, as usual, you need to convert text to string to use <code>putStrLn</code> (don't just use <code>show</code>, as it will include quotes and escape sequences, which <code>dot</code> will not understand)</p> <pre><code>putStrLn $ unpack outputText </code></pre> <p>Putting this all together, the final program createDotFile.hs would be</p> <pre><code>import Data.Text.Lazy import Data.GraphViz import Data.Graph.Inductive.Example import Data.GraphViz.Printing main = putStrLn $ unpack $ renderDot $ toDot $ graphToDot nonClusteredParams clr479 </code></pre> <p>Compile using <code>ghc createDotFile.hs</code> (remember to cabal install the required packages, as well as graphviz itself if you want to do anything with the output). On the commandline, you can now pipe the output of this program to <code>dot</code>, which will convert this to a usual format.... For instance, here I convert to svg</p> <pre><code>./createDotFile | dot -Tsvg &gt; graph.svg </code></pre> <p>which on my linux box can be viewed by typing</p> <pre><code>eog graph.svg </code></pre> <p><img src="https://i.stack.imgur.com/QQgMd.jpg" alt="visualization of clr479"></p> <hr> <p>Edit-</p> <p>To clarify, the output of the haskell program needs to be provided as an input to GraphViz. The msi file to install graphviz on windows here <a href="http://www.graphviz.org/Download_windows.php" rel="nofollow noreferrer">http://www.graphviz.org/Download_windows.php</a>.</p>

    1. COFirst of all,would like to thank you because it runs without generating any errors. But the thing is I'm doing this on windows , not on Linux. So, do you know how I can view the graph ? I'll paste the output I get above in my question under something called "EDITED"

    2. COAccording to the hackage description- "This is the top-level module for the graphviz library. It provides functions to convert Graphs into the Dot language used by the Graphviz suite of programs (as well as a limited ability to perform the reverse operation)." So, according to this, the output of a Data.Graph program is another program that must be processed by the `dot` program, which is a part of GraphViz. In other words, you will need to install GraphViz/dot on your computer and use that to create an actual graph (ie- as an svg).

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.
