This example displays a single grade level from a dataset comparing "needed" and "averaged" values across grades. The visualization starts by showing the grade name "Kindergarten" as a header, pulled directly from the data file using JavaScript. Built with D3 v5 and a custom data module, the code parses a JSON array and accesses the first record's `grade` property via `JSON.parse`. The page then updates the HTML heading's text content through `document.getElementById` and `textContent`, demonstrating a basic data-to-DOM binding. The chart itself does not render any visual elements beyond this text output.

D3: Linked charts

A bar chart displays student grades from a dataset of student IDs and numeric grade values, with each bar representing a student. The visualization uses linked charts to show grades and allows sorting by ascending or descending order. Built with D3.js, it uses SVG rendering with animated bar transitions and axes. The bars are color-coded using hue and saturation, and hovering highlights individual bars to reveal exact grade labels. The data appears to be sample grade records with student IDs, and the chart is designed to compare grade distributions across students.

reading csv v5

This example visualizes a simple bar chart of student grades from a CSV file. It shows the relative performance of eleven students by mapping each grade value to a bar’s width. The code loads the data with `d3.csv` from the local file `votiOne.csv`, then appends SVG `<rect>` elements to a 500×500 canvas. Each rectangle’s width is set from the `Grade` field, while the `y` position and height are calculated from the data index, creating evenly spaced horizontal bars. The chart uses D3 v5’s promise-based `.then()` method to handle the asynchronous data loading.

Hello VizHub

A data visualization renders a simple scatter plot of student grades from a CSV file, displaying each name and grade as a point on a chart. The visualization uses D3.js version 5, specifically the `select`, `csv`, `scaleLinear`, and `axisBottom` APIs to read the data, map values to coordinates, and draw the x-axis. The SVG-based chart is 500 by 500 pixels, with a single large circle overlaid as a decorative element. The grade data is parsed as numbers before being mapped to the horizontal axis.

Untitled

This bar chart displays the number of students for various grades and locations, with bars colored blue and axes labeled "Grades" and "Num_students." The visualization uses D3.js v6 to create an SVG rendering, employing `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the numeric y-axis. Data is hardcoded in an array of objects, while axes are generated with `d3.axisLeft` and `d3.axisBottom`. The chart includes a pink background rectangle and console logs for debugging scale behavior.

Untitled

This example shows a horizontal bar chart comparing marks across grade categories (Grade_A through Grade_F) using a CSV data source. Each bar is color-coded based on its mark value via the `colourPicker` function, and hovering with the mouse triggers an animated enlargement of the bar while displaying a tooltip with the mark and grade. The visualization uses D3 v4 with SVG rendering, `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis, and transitions via `transition.duration` and `transition.delay` for the initial render and hover interactions.

Untitled

This example shows the distribution of student counts across letter grades, with horizontal bars colored in a solid blue tone. The chart uses D3.js v6 to construct an SVG visualization, employing `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the categorical y-axis. It renders rectangles whose widths are proportional to `num_students` values, with axes generated via `d3.axisLeft` and `d3.axisBottom`. The data is hardcoded in the script rather than loaded from the available CSV file.

Gist 062e2198aa30fcbc94657e1e50de22e5

This interactive line chart uses D3.js to show grade-to-grade transition rates for British Columbia school students, with dropdown menus to select a demographic group and a comparison group. An animated slider scrubs through school years, triggering a brush interaction that updates the chart display. The visualization relies on D3’s time scale, linear scale for the slider, and SVG axes, while Bootstrap and Bootstrap Select handle the interface styling. The data appears to be sourced from the BC Ministry of Education’s public dataset on grade transitions.

Students Grades of Bar Chart

This horizontal bar chart displays student grades, with each student’s name on the y-axis and their corresponding numerical grade on the x-axis. The visualization uses D3 v5’s `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to render the SVG bars. Data is loaded from a CSV file, and interactive features include tooltips on mouseover and an alert on click, triggered via `select` and event listeners. Grid lines and axis labels are conditionally configured through a chart configuration object.
