Although this plugin is not yet complete as a practical tool, I am going to post it here, and recommend as best innovation prize at MoodleMoot 2026.

VizPort is a (Block Type) plugin for visualizing and displaying data recorded in Moodle's database. Its key feature is that visualization methods can be expanded by adding visualization units. Visualization units are written in JavaScript. By assigning an index and calling a specific function within the JavaScript, we can retrieve data recorded in Moodle's database and store it in a JavaScript object, which can then be used to draw whatever visualizations each user needs.
We would like to make it possible for course administrators to upload visualization units, but this has not been implemented yet. Currently, they need to be placed as regular files in the vizport/js directory.
The part that retrieve data from the database and passes it to the JavaScript side is not modularized; it is hardcoded in fetchdata.php, one of the plugin's constituent files. The reasoning behind this is that only those with permission to modify server files should be able to make changes to this part for security.
On the demo site (sorry it's HTTP), please access it as a guest. The password is 'nikutamasoba'. VizPort can be accessed from the right sidebar. There is an option to specify a date/time range for the logs, but you can leave it blank (it will cover the entire period).
[Update 2/28] I was wrong to say, "you can leave it blank, and it will cover the entire period". Sorry about that. If nothing is specified, the access logs were being fetched only for the current day, while the grade data was being fetched in full, regardless of date specified. Since the demo course was conducted in 2023, I changed the default date range to 10/1/2023–12/1/2023. This affects the "アクセス棒グラフ (Bar chart of student access)" I think it will take about 20 seconds to fetch the logs and render the graph. [/Update]
