This dashboard for a school's 2025 forecasted performance combines multiple interactive D3.js visualizations into one screen. It shows key statistics, a pie chart of subject performance, a bar chart of average grades by class, and an interactive piano that maps subjects to musical keys with color intensity reflecting grades. A schematic school floor plan positions classes using circle sizes for student population. The code uses D3's `rollup`, `scaleBand`, `scaleLinear`, `scaleOrdinal`, `pie`, `arc`, and TopoJSON for rendering.

School Performance Dashboard

This visualization presents a forecasted analysis of our school's class performance across various departments for the year 2025. The dashboard offers multiple visualizations to help identify trends i

Visualizations Included

  1. Key Statistics Panel: Provides an overview of total classes, total students, average grades, and the most popular subjects and highest-performing classes.

  2. Subject Performance Distribution: A pie chart breaking down the performance distribution across different subject areas in the school.

  3. Average Grade by Class: A bar chart showcasing which classes achieved the highest average grades.

  4. Performance Piano Visualization: An interactive piano that maps subject performance to musical keys, with color intensity reflecting average grades.

  5. School Floor Plan: A map visualization displaying the layout of the school, with circle sizes indicating student population and performance.

Data Notes

This visualization uses forecasted data for 2025 and is intended for demonstration purposes only. In a real-world scenario, this would be populated with actual enrollment and performance data.

How to Use

  • Hover over chart elements to see more details.
  • The piano visualization maps subjects to piano keys, with brighter colors representing higher grades.
  • The school map provides tooltips with detailed information about each class's performance.
  • Analyze patterns across different subjects and class locations.

Technologies Used

  • D3.js for interactive visualizations
  • JavaScript ES6
  • TopoJSON for map rendering

Fork of Blank Slate with Hot Reloading

This interactive stacked bar chart visualizes the 2024 Times Higher Education World University Rankings, displaying scores for teaching, research, citations, industry income, and international outlook across top universities. Built with D3 v5, the visualization uses `d3.stack` and `d3.scaleBand` to compose the bar segments, with color-coded legends that toggle categories on and off. The chart includes dropdown menus for sorting by various metrics, previous/next navigation buttons, and hover tooltips revealing detailed scores for each institution, all rendered as SVG elements with animation support.

Fork of Blank Slate with Hot Reloading

This example demonstrates the VizHub V3 runtime environment's blank slate template, which supports continuous hot reloading through interactive widgets. The code loads a CSV dataset of school scores from a GitHub gist into a p5.js table using `loadTable`, then visualizes the economy (mpg) column as a scatter plot of circles positioned along the x-axis by their value. The sketch renders to an 800×800 canvas via `createCanvas` and iterates through the data array in the `draw` loop to display each point.

Fork of Blank Slate with Hot Reloading

This example displays a pie chart of regional sales data from a CSV file, with each slice’s percentage labeled and a legend listing regions and their shares. It uses D3’s `csv`, `pie`, `arc`, and `scaleOrdinal` to fetch data, compute slice geometry, and map colors. The chart is rendered into an SVG, with the VizHub V3 runtime handling data loading and hot reloading.

Fork of Blank Slate with Hot Reloting

This interactive D3.js visualization depicts a stylized rainbow scene with the sun and clouds in a sky above grass. The code creates an SVG scene where hovering over a rainbow band brightens its color, clicking a band triggers a white flash and a sparkle effect, clicking the sun makes it spin and pulse, and clicking clouds moves them. The visualization is implemented using D3.js `select`, alongside custom path drawing for the rainbow's arc bands, to generate the interactive SVG elements.

Fork of Fork of STUDENT'S SPORTS DATA VIZ

This visualization displays individual student subject scores as orange bars alongside skyblue bars representing the average score for each favorite subject. The bar chart animates upward on load using D3 transitions, with hover interactions changing bar color and showing a tooltip with the exact score. The code uses d3.text to load tab-separated data from a GitHub gist, d3.rollup to compute means, and d3.scaleBand with d3.axisBottom and d3.axisLeft to render the SVG chart.

Fork of STUDENT'S SPORTS DATA VIZ

This visualization displays student test scores across favorite subjects, combining an animated orange bar chart with a static skyblue overlay showing average scores per subject. The code loads tab-separated data from a GitHub gist via `d3.text`, parses it into objects, and uses `d3.rollup` to compute subject means. It renders SVG bars with transitions, axes via `d3.axisLeft` and `d3.axisBottom`, and includes hover tooltips using D3 event handlers. The chart animates bars rising from the baseline using `.transition()`, and tooltips display individual subject and score data.

Fork of Blank Slate with Hot Reloading

This example demonstrates a simple D3 bar chart in the VizHub V3 runtime, showing how a responsive SVG visualization adapts to its container’s measured width and height. The chart displays categorical data with names A–E and corresponding values, using `d3.scaleBand` for the x-axis and `d3.scaleLinear` for the y-axis, with axes rendered via `d3.axisBottom` and `d3.axisLeft`. The code illustrates the hot-reloading workflow by exporting a `main` function that receives the container element and draws the chart using an enter/merge/exit pattern, enabling live updates as the data or layout changes.

Fork of HTML Starter

A pie chart displays the distribution of 110 students across five grade categories (A through E), with labeled slices showing category counts and a legend describing letter-grade ranges. Built with D3.js v7, the visualization loads a CSV file, uses `d3.rollup` to aggregate student counts by category, and employs `d3.pie` and `d3.arc` to generate SVG paths. A color scale colors each slice, while labels and legends are added programmatically to the SVG.
