Harvard/MitX Video Views

Harvard/MitX Video Views

This visualization shows the number of video view events for courses from HarvardX and MITX during the 2013 academic year. It uses a bar chart with courses sorted descending by view count and color-encodes whether the course was certified. The visualization is built using the vega-lite-api library on top of vega-lite and vega, with data loaded from a TSV file via d3.tsv. The appearance is customized through a configuration object that adjusts axis colors and font sizes for readability.

Harvard/MitX Video Views

This chart aggregates total video views per course from a Harvard/MITx person-course dataset, using color to encode engagement categories and sorting courses by descending view counts. Built with the vega-lite-api, it declares a bar mark with quantitative x-axis sums and categorical y-axis fields, then renders through Vega-Lite’s SVG renderer. The visualization loads data via d3.tsv and applies custom axis styling from a config object.

Harvard/MitX Video Views

This bar chart displays the distribution of video views in Harvard/MITx courses by student status. The visualization uses a single bar mark, with student-status mapped to the x-axis and the count of records on the y-axis. Built with vega-lite-api and rendered through Vega-Lite, the view fetches a CSV from a GitHub gist via d3.csv, and applies custom axis styling from a config file. The chart auto-fits to the window dimensions.

Harvard/MitX Engagement

A pie chart visualizes engagement by counting video view events per HarvardX/MITX course from the 2013 academic year. The chart encodes course ID on the y-axis and view counts on the x-axis, with color mapping to engagement categories and tooltips showing course identifiers. Built with the vega-lite-api library on d3.v5, it loads tabular data from a CSV file hosted on GitHub, with appearance adjusted via a custom config object for axis and label styling.

Messin - EdX Video Views by Country, AY2013

A stacked bar chart shows total video views for each HarvardX and MITx course in the 2013 academic year, with each bar segmented by country. The visualization is built using the vega-lite-api, which registers vega and vega-lite for rendering. Data is loaded via d3.csv from a GitHub-hosted dataset derived from the MITx-HarvardX Dataverse. The chart uses summed nplay_video values per course, sorts courses by total views, and enables tooltips on hover. The dark-themed configuration customizes axis labels and title styling.

EdX Viewer Data by Course and Country, AY2013

This stacked bar chart shows total video views for HarvardX and MITx courses during the 2013 academic year, with each bar segmented by viewer country using a sinebow color scheme. The visualization uses vega-lite-api with d3.csv to load course and country data from the MITx-HarvardX Dataverse, then renders interactive tooltips via vega-tooltip. Bar height encodes summed video views per course, sorted descending, while the configuration adjusts axis styling and label font sizes for readability.

EdX Viewer Data by Course, AY2013, AY2013

This visualization displays the total number of video views per viewer, aggregated by course, for HarvardX and MITx courses in the 2013 academic year from the MITx-HarvardX Dataverse. It uses a stacked bar chart with a sinebow color scheme, where each bar segment represents a distinct course. The Vega-Lite API, built on D3, renders the chart in SVG, with axis and label styling customized in a separate config file. Data is loaded asynchronously via D3’s `csv` method from a GitHub-hosted dataset.
