Student to Teacher Ratios - Ratio by Education Type

This visualization displays student-to-teacher ratios across different education types as a scatter plot, with each dot representing a country positioned by education category and ratio value. The points use partial opacity to reveal data density, while tooltips identify outlier countries by name. Built with the Vega-Lite API on top of D3.js, the chart loads CSV data from a Tidy Tuesday dataset and uses a custom configuration to adjust axis and label styling.

AI-generated description

This visualization was constructed using the vega-lite-api. It was originally forked from one of Curran Kelleher's Vega-Lite API templates and modified to include Student to Teacher Ratio data which originates from R for Data Science's Tidy Tuesday weekly event for May 7, 2019.

This chart shows Student to Teacher Ratio by Education Type. My goal was to use a simple metric as a starting point for visualizations, and I hoped to see an interesting correlation. I introduced some opacity to allow the concentration of data points to be better expressed.

The graphic gives a rough idea. Primary Education is not as concentrated as the other categories. However, with this much data crammed into one chart, it's hard to make generalizations. It does highlight outliers, which can be identified by tooltip.

D3 Scatter Plot for Education rate of Student

This D3 scatter plot shows the student-to-teacher ratio across different countries over time, with each circle representing one country-year observation. The data comes from the Global Economy rankings via a tidytuesday GitHub dataset, loaded as CSV with d3.csv. The visualization uses d3.scaleLinear for both the x-axis (year) and y-axis (student ratio), along with d3.axisLeft and d3.axisBottom to render the axes. Circles are drawn in SVG with semi-transparent fills, positioned using the projected coordinates from the scales.

This example loads a student-to-teacher ratio dataset from a CSV file and displays summary statistics about the data, including its size in kilobytes, row count, and column count. The visualization uses the D3.js library (v5) to fetch and parse the CSV via `d3.csv`, then formats the results using `d3.csvFormat`. A large `<pre>` element shows the computed metrics in text form. The dataset, sourced from Tidy Tuesday, contains country, year, educational level, and ratio fields, though the current code only reports dataset dimensions rather than rendering charts or graphs.

The ratio of students in the country bar plot

This bar plot shows the student-to-teacher ratio for every country-year pair in a global education dataset. Each vertical bar represents one country-year combination, with bar height mapped to the ratio value, while the x-axis lists concatenated country codes and years. The visualization uses D3 v7’s `scaleBand` and `scaleLinear` to position and size rectangles, and loads data from a CSV file via `d3.csv`. The data originates from the Global Economy rankings and was consolidated through a TidyTuesday GitHub repository.

The ratio of students in the country (Primary Education)

This visualization shows the ratio of students in primary education across countries, with bars sorted in descending order to highlight the highest ratios. A bar chart rendered with SVG uses D3 v7’s `scaleBand` and `scaleLinear` to position and size the rectangles, while `d3.axisBottom` and `d3.axisLeft` display the country-year labels and ratio scale. The data is loaded from a CSV file sourced from the Global Economy and tidytuesday dataset, with bars colored steelblue and axis labels added via SVG text elements.

Pupil-Teacher Ratio by Country (UN Stats), using D3.js

This bar chart displays the pupil-teacher ratio in secondary education for each country in 2015, sourced from UNESCO data. The visualization uses D3.js to create the SVG graphic, sorting countries by ratio and rendering them as horizontal bars. Specific D3 APIs include `csv` for data loading, `scaleBand` and `scaleLinear` for axes, `axisLeft` and `axisBottom` for chart scaling, with the final rendering handled via SVG `rect` elements.

Scatter Plot

A scatter plot displays the students-to-staff ratio for various countries, with each red circle representing a country's ratio plotted against the country name on the x-axis. The D3 v7 code loads CSV data from a GitHub Gist, then uses `d3.scaleBand` and `d3.scaleLinear` to map country names and ratios to SVG coordinates. Axis labels and rotated tick text clarify the chart, with the y-axis showing the ratio and the x-axis listing countries.

Scatter Plot

This scatter plot shows the Students to Staff Ratio for universities across different countries. It uses D3.js (version 7) with an SVG rendering approach to display each country as a red circle, positioned along a categorical x-axis for country names and a linear y-axis for the ratio values. The code loads data from a CSV file via a GitHub gist URL, and employs D3's `scaleBand` and `scaleLinear` functions to map the data coordinates, along with `d3.axisLeft` and `d3.axisBottom` to generate the axes.

fm viz - students vs ratios

This visualization shows student-to-teacher ratios across different students using two overlaid line charts, comparing two quantitative variables (d and e) for each student name. The data comes from a CSV file referenced from the UCI Machine Learning Repository. Built with Vega-Lite API and d3, the code uses vega-lite-api’s `markLine` and `encode` methods to map the categorical student names to the x-axis and the quantitative values to the y-axis, with the second line layered on top using `vl.layer` to combine both series. The visualization is rendered as an SVG, with custom styling for axes and labels defined in a configuration object.
