Everyone likes data visualizations so I wrote a plugin that will make the quick and secure creation of Pie Charts, Bar Charts and Line Charts easy. The answer is: Easy Graphs.
Easy graphs is very simple to use. It’s a shortcode – [easy_graphs]
Not just like that. The shortcode also requires one parameter “data”. This parameter is a comma separated list of number values “1,2,3,4,5,6,7”.
You can also add a “type” parameter. The “type” can be “line”, “bar” or “pie”. “bar” is the default.
For a Bar graph, you can optionally pass additional parameters: width, height, and color.
Example: [easy_graphs height=”200″ type=”bar” data=”30,70,65″]
By default, width and height are populated from your media embed sizes that are set in your Settings > Media menu inside WordPress. Color should be a hex color code.
For a line graph, the options are similar: color1, color2, height and width.
If you will: [easy_graphs height=”200″ type=”line” data=”200,150,175,260″]
In this case, color1 is the “fill” color and color2 is the line color. Both should be hex.
For Pie charts, there are some additional limitations but fewer parameters: color1, color2 and diameter.
Try this: [easy_graphs diameter=”150″ data=”40,60″ type=”pie”]
Diameter should be an integer represented in pixels. Color1 and color2 are the fill colors of the pie slices. The limitation is the pie chart, at this time, can only take 2 values. I’ll work on that.
On the roadmap are other things. Make the pie chart take more values than just 2. Maybe include other graph types. Labels so the data can be more easily understood.
What would you add to this?

Easy Graphs

This plugin allows for simple data visualization in post content. It is Multisite compatible and relies on shortcodes to render the graphs.

A WP site has posts, custom posts, users and taxonomy terms. The Connectome shows them all in a single interactive visualization as nodes and links of a graph. Also, we calculate some importance measure for these nodes and display it in the nodes sizes. The Connectome, then, should provide insight about the structure of your site and a different navigation, mostly interesting for the site admin but perhaps also, after some configurations, good to show to your visitors.
I think The Connectome could be useful to novice WP site creators because it will help you learn all the essential elements in your site and how they connect to each other.
The “importance measure” for the nodes is the <code>degree centrality</code>, that is, how many links touch the node.
This is the first release of my first plugin so I’m very exited and scared, but also quite open to suggestions, requests or criticism. I would be especially happy if more experienced developers inspected my code and gave me their opinions.
<h3>Live demo</h3>
It’s for a small site, but anyways

<h3>Road map</h3>
I have a long list of improvements to include in future releases, among them:
<ul>
<li>Responsiveness and more flexible behavior for the visualization</li>
<li>Search functionality to find nodes in the graph</li>
<li>Having several graphs with different configurations to show in different parts of your site</li>
<li>Tell the admin about problematic nodes like posts without featured image or excerpt text, taxonomy terms without description, etc.</li>
<li>More interesting importance measures like the eigenvalue or the betweeness centralities, perhaps allowing the user to pick which one to use</li>
<li>Multilingual support, right now it’s only English. Besides making it translation ready, this will also imply to make the plugin compatible with multilingual plugins like Polylang or WPML</li>
</ul>
If you think one of them is more urgent thant others, you can also tell me.
<h3>Performance</h3>
The good news is that, once the graph is created, it’s stored on the DB and and used until you save the options again in the options page. However, to build the graph we first include all the elements (but those manually disabled) and then connect them to calculate the centrality and evaluate which are the most important. Only then we reduce the elements, using the centrality as the metrics. That means a very big site (with many users, posts and terms) will require a lot of resources and time to create the graph, even if it ends up having few elements. Only when the elements are manually disabled they don’t participate on the graph creation. Probably if you have a very big site you would have a server with ample resources, but if you don’t, then probably is not a good idea to use The Connectome until the implementation changes.
