The narrative visualization should follow one of the three effective narrative visualization structures:
a martini glass, where the message is delivered without allowing user exploration until the end,
an interactive slideshow, where user exploration is allowed at some or all of the steps of the story, or
a drill down story. which presents an overview and allows the user to explore different storylines from there.
You must use the D3 library to construct your pages. You cannot use Tableau Stories, Vega, Vega-Lite, Ellipses or any other high-level tool designed for data visualization to implement your narrative visualization.
The narrative visualization should be built with scenes, annotations, parameters, and triggers.
The scenes should follow a template for visual consistency and follow an order to best convey the message. One way to implement different scenes is to make each a separate web page. Another way is to use [login to view URL](id).html = "" to clear the contents of a container element (e.g. an SVG element) and then repopulate that element using .append().
An essay will be required and will be submitted along with the URL of the narrative visualization. This essay is an important piece of the assignment as it is used for you to communicate your understanding of the concepts of narrative visualization and how they apply to the one you created.
The essay should contain the following sections.
Messaging. What is the message you are trying to communicate with the narrative visualization?
Narrative Structure. Which structure was your narrative visualization designed to follow (martini glass, interactive slide show or drop-down story)? How does your narrative visualization follow that structure? (All of these structures can include the opportunity to "drill-down" and explore. The difference is where that opportunity happens in the structure.)
Visual Structure. What visual structure is used for each scene? How does it ensure the viewer can understand the data and navigate the scene? How does it highlight to urge the viewer to focus on the important parts of the data in each scene? How does it help the viewer transition to other scenes, to understand how the data connects to the data in other scenes?
Scenes. What are the scenes of your narrative visualization? How are the scenes ordered, and why
Annotations. What template was followed for the annotations, and why that template? How are the annotations used to support the messaging? Do the annotations change within a single scene, and if so, how and why
Parameters. What are the parameters of the narrative visualization? What are the states of the narrative visualization? How are the parameters used to define the state and each scene?
Triggers. What are the triggers that connect user actions to changes of state in the narrative visualization? What affordances are provided to the user to communicate to them what options are available to them in the narrative visualization?
