Messin - EdX Video Views by Country, AY2013

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.

EdX Viewer Data by Course and Country, AY2013

This stacked bar chart shows the total number of EdX video views for each country during AY2013, with each bar segment color-coded by course. The visualization uses the vega-lite-api to build a bar mark with an aggregate sum of `nplay_video` on the y-axis and country on the x-axis, sorted by total views. A sinebow color scheme distinguishes courses, and tooltips display the aggregated view counts per segment. Data is loaded from a CSV file hosted on GitHub, originally sourced from the MITx-HarvardX Dataverse, with custom axis and label styling via vega-lite configuration.

Harvard/MitX Video Views

This stacked bar chart visualizes video-view events across HarvardX and MITx courses on EdX for the 2013 academic year, with each bar segmented by three levels of student engagement, from courseware access to certificate achievement. The visualization uses the Vega-Lite API, with vega-lite’s mark-bar encoding x by course, y by summed video plays, and color by engagement level. Data is loaded asynchronously via d3’s tsv method from a CSV hosted on GitHub, and the rendered SVG is customized using a config object for axis styling.

EdX Viewer Data by Course with Stacked Bars, AY2013

A stacked bar chart displays total video view counts per EdX course for the 2013 academic year, with each bar segment colored by country of origin. The visualization uses the vega-lite-api to encode course on the x-axis, summed video views on the y-axis, and country as the color channel, rendering with vega-lite and vega. Data comes from the MITx-HarvardX Dataverse CSV, fetched via d3.csv. The chart applies a sinebow color scheme and a custom dark config for axis styling and tooltip appearance.

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.

EdX Video Views by Country, AY2013

This stacked bar chart shows total EdX video views by country for the 2013 academic year, with color encoding distinguishing countries. The visualization uses the vega-lite-api to construct the chart, with `vl.markBar`, `vl.y().fieldQ('TotalViews')`, and `vl.x().fieldN('Countries').sort('y')` specifying bar marks and quantitative/ordinal encodings. Data is loaded asynchronously via `d3.csv` from a GitHub-hosted CSV originating from the MITx-HarvardX Dataverse. The chart is rendered with Vega, Vega-Lite, and Vega- Tooltip, customized through a config file that adjusts axis styles and label formatting.

EdX Viewer Data by Course with Stacked Bars, AY2013

This example uses stacked bars to show the total number of video plays per course on EdX for the 2013 academic year, with each bar segment colored by the view counts’ country of origin, revealing the geographic distribution of engagement for each course. The visualization is built with the vega-lite-api, which registers Vega and Vega-Lite, and it loads CSV data from a GitHub-hosted dataset derived from the MITx-HarvardX Dataverse. The chart sums the ‘nplay_video’ field across courses, sorts courses by total views, and applies a sinebow color scheme to the country categories, with a custom config adjusting axis and label styling.
