Zegami is really great for exploring large collections of images, but what about data sets that don't have images?
So that everyone else doesn't miss out, we've created dynamic, data-bound images that we like to call Zegs! Zegs are great because they open up Zegami's intuitive interface for data exploration to any kind of data imaginable.
Zegs can be as simple as a square with a coloured background, where that colour represents a value from the data.
Or they can be something more complex, containing text, gradients, images and charts. Just like a baseball card!
The great thing about Zegs is that they are bound to the data, meaning as the data changes so does the tile. In addition, Zegs can show different levels of information based on their size and zoom level.
Creating a simple Zeg
Creating a Zeg is a relatively straightforward process and is almost exactly the same as creating an image collection.
Lets look at all the register of all registered local bus services in Great Britain. You can download the entire data set from http://www.vosa.gov.uk/vosa/apps/olbs/Bus_RegisteredOnly_D.csv
Just like in the guide Creating your first collection the first step is to create a collection, give it a name and upload the csv data file.
Then jump ahead to Zeg styling options and select Design Zeg. The Zeg designer is a simple tool for creating simple Zegs. With it you can set a text label and the background colour of the Zeg.
For our bus data set lets set the Licence Number (Lic_No) to be used as the display text. The text colour and alignment can also be changed.
Once that is set we can also set the background colour.
The default background colour is set to White, but the colour can also be set to the values in a column. From the drop down list select Service_Type_Description to automatically assign a colour based on each categorical value. For columns that contain less than 32 distinct values the Zeg designer can assign an automatic colour.
Each time a setting is changed in the Zeg designer the preview window is updated.
When the Zeg is ready click COMPLETE to finish the collection and view it instantly.
Creating an Advanced Zeg
Advanced Zegs are able to unlock the true power of Zegami by being able to show complex graphics, images and colours all bound to the source data set. In order to create an advanced Zeg some technical knowledge of SVG and XSLT is required. See out guide on Advanced Zegs to learn more or contact us at firstname.lastname@example.org for assistance.
