This interactive grouped bar chart displays the number of students per grades (A, B, C) across different depression levels, using data from a CSV file on student grades and mental health. The visualization uses D3.js v7 and the `d3.scaleBand`, `d3.scaleLinear`, and `d3.axisBottom` APIs for layout. Bars animate in on load via the `transition` method, and hovering reveals a tooltip with exact counts. A clickable legend toggles grade visibility by adjusting bar opacity.

GroupedBarchart

This grouped bar chart compares anxiety levels across school grades and genders. The visualization displays clusters of bars for each grade, with individual bars representing male and female students, and color distinguishes anxiety severity categories. The code uses D3.js v7 with `d3.scaleBand` for grouping, `d3.scaleLinear` for the y-axis, and `d3.axisBottom`/`d3.axisLeft` for axes. Hover interactions trigger tooltip updates via `d3.select`. Data is pre-aggregated in the script, rendered as SVG using `d3.select` and `append` methods.

Projec2

This example shows how student depression levels relate to their grades using a bar chart and a pie chart. The bar chart visualizes each student's depression level with color-coded bars, while the pie chart displays the distribution of depression levels across the dataset. Both charts use D3 v7's `d3.csv` to load data, `scaleBand` and `scaleLinear` for axes, and `d3.pie` and `d3.arc` for the pie slices. Interactive tooltips appear on hover, and the bar chart uses an event-driven `transition` for the tooltip's opacity changes.

final project

This bar chart displays the average student grades (on a 3-point scale where A=3, B=2, C=1) grouped by self-reported stress level, sorted from highest to lowest average grade. The visualization uses D3 v7’s `d3.csv` to load remote CSV data about student grades and mental health, then applies `d3.group` and `d3.mean` to aggregate values. Rendered as SVG rectangles with a `d3.scaleBand` x-axis and `d3.scaleLinear` y-axis, bars change color on hover via CSS.

two bar charts

This visualization shows the distribution of current student grades (A, B, C, D, F) across three stress levels (Low, Medium, High) using a single bar chart. Users can click legend items to filter the display to a specific grade, highlighting the selected legend entry and updating the bars accordingly. The chart loads CSV data via d3.csv, aggregates counts and averages (study hours and social media platforms) per grade-stress combination, and renders SVG bars with a tooltip. Built with D3 v7, it uses d3.mean for aggregation and d3.select for DOM manipulation.

radialbarchart

This radial bar chart displays the distribution of grades (A, B, C) across different anxiety levels, using concentric rings where each ring represents an anxiety level and each arc segment corresponds to a grade's proportion of the total. The visualization uses D3.js (v7) with SVG and animation, employing `d3.arc()`, `d3.scaleOrdinal()`, and `d3.csv()` to load and process data from a GitHub gist. Interactive tooltips and legend hover effects highlight grade-specific arcs using `transition()`.

final project

A grouped bar chart displays the distribution of letter grades (A through F) across five self-reported stress levels, using counts from a CSV dataset of student grades and mental health. The visualization reveals how grade frequencies vary by stress category. The code uses D3 v7 with `d3.csv`, `d3.rollups`, and `d3.scaleBand` for the nested bar layout, plus SVG rendering for all marks and axes. An ordinal color scale maps grades to categories, with a legend provided.

final project

This bar chart shows the average grades of students grouped by their self-reported stress levels (Low, Medium, High). The visualization uses d3.csv to load a remote dataset, d3.rollup to aggregate the grade means, and d3.scaleBand with d3.scaleLinear to map stress categories and grade averages to the SVG coordinate system. Bars are rendered as SVG `rect` elements, with axis labels and rotated x-axis tick text for readability. The chart highlights the relationship between mental health and academic performance.

Final project

This bar chart shows the relationship between students’ self-reported anxiety levels and their average grades, with anxiety ordered from “Very Low” to “Very High.” The visualization reveals how average grades shift across these five categories. Using D3 v7, the code loads a CSV from a GitHub gist, groups the data with `d3.rollup` to compute mean grades per anxiety level, and renders an SVG with `d3.scaleBand` and `d3.scaleLinear` axes. Bars change color on hover, and rotated x-axis labels improve readability.
