In 2014 – 2015, the Ministry of Children and Youth Services (MCYS) defined five Service Regions and thirty-three Children and Youth Mental Health (CYMH) Service Areas in Ontario.
We have used free and open source software (FOSS) to convert the Ontario government’s Shapefile archives of the geographic boundaries of these MCYS Service Regions and CYMH Service Areas into TopoJSON files that are convenient for visualizing these geographic bodies and their various characteristics (e.g. population, population density, rate of population growth, etc).

We have used D3-GEO to transform our TopoJSON files into (a sample of) area, regional, and provincial views of the MCYS Service Regions and CYMH Service Areas in Ontario:
In previous posts, we compiled and shared a wealth of data and metadata connected with Ontario’s government-wide Data Inventory and Data Catalogue. These materials lay the groundwork for – and hopefully inspire – the study of the early development of an open data initiative undertaken by a sizable, democratic sub-national government.
Our final contribution (for now) to kick-starting this study is to share a few ways of visualizing the Ontario Government’s Data Inventory.
edges connecting source nodes and target nodes represent the relationship hasPublished; and
a target node’s colour (e.g. lime, yellowgreen, red, white) represents the Access Level of the corresponding Dataset (Open, To Be Opened, Restricted, Under Review).
Figures 1 and 2 represent Ontario’s Government-wide Data Inventory on July 29,2016 (its inception) and September 1, 2017, respectively.

We may also animate the Data Inventory’s evolution over time:
Finally, let’s add some functionality (tooltips and hyperlinks) to our visualization of the Data Inventory, so that users may explore and click on nodes to access the rich content about datasets on the web pages served by the Data Catalogue’s API.
