This visualization presents a side-by-side bar chart comparing student grades across different sleep patterns, with the bars for each sleep category grouped by grade level. The chart is built using D3.js v7, which loads a CSV file from a GitHub gist, groups the data with the `d3.rollups` API, and scales using `d3.scaleBand` and `d3.scaleLinear`. Hovering over a bar triggers a tooltip that displays the sleep pattern, grade, and count, with the visualization rendered as SVG elements.

grades vs sleep

This grouped bar chart visualizes how students' grades (A, B, C, D, E) correlate with their self-reported sleep patterns (e.g., Good, Fair, Poor). The chart uses a D3.js v7 SVG renderer with `d3.scaleBand` for the categorical axes and `d3.scaleOrdinal` with `d3.schemeSet2` for color. It reads a CSV from a Gist, aggregates counts with `d3.rollups`, and displays a tooltip on hover.

Fork of grades vs sleep

This vizhub fork displays a grouped bar chart of student grades (A, B, C, D) across different sleep pattern categories. The chart shows the number of students in each grade category for each sleep pattern, with color-encoded bars for each grade level. Built with D3 v7, the code uses `d3.csv` to load a Gist-hosted dataset, `d3.rollups` for aggregation, `d3.scaleBand` and `d3.scaleLinear` for axes, and `d3.schemeSet2` for color encoding. The visualization includes axis labels, a title, and a tooltip on mouseover.

Fork of grades vs sleep patterns

This example visualizes student grade distributions across sleep patterns using interactive pie, bar, and grouped bar charts. The SVG-based visualization uses D3 v7 APIs including `d3.rollup` for data aggregation, `d3.pie` and `d3.arc` for the donut chart, and `d3.scaleBand` with `d3.axisBottom` for bar rendering. Users switch between chart types via buttons, while mouseover events trigger tooltips displaying category counts. Data comes from a CSV file containing student grades and mental health information.

sleep vs concenration

This grouped bar chart compares sleep patterns against concentration difficulty levels, showing the number of students for each combination. The data comes from a CSV file on student grades and mental health, loaded via `d3.csv`. The visualization uses `d3.rollups` to aggregate counts by two categorical dimensions, then renders the nested groups with `d3.scaleBand` for both axes and `d3.scaleLinear` for the y-axis. Colors are assigned using `d3.scaleOrdinal` with `d3.schemeTableau10`. SVG rectangles display the bars, with hover tooltips showing exact counts for each sleep and concentration category.

Assignment 3

This visualization compares average screen time, sleep hours, and GPA across six student groups using a combined bar and line chart. Gray bars represent average screen hours, while blue, green, and red lines depict trends for screen time, sleep, and GPA, respectively. The chart uses D3’s `scaleBand` for categorical x-axes, `scaleLinear` for the y-axis, and `d3.line` to connect summary points. Data is loaded from a CSV via `d3.csv`, grouped into six slices, and aggregated with `d3.mean` to compute group averages.

SleepData

This visualization compares recommended sleep hours against average reported sleep hours for students from kindergarten through 12th grade. Each grade level displays two horizontal bars, with teal representing averaged sleep and orange representing needed sleep, alongside a legend and axis labels. The chart uses React with D3 v5, employing `scaleLinear` for the x-axis, `scaleBand` for the y-axis, and `d3.schemeSet2` for color encoding. The data is embedded as JSON and rendered as SVG rectangles within a fixed 960×500 viewport.

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.

1

This stacked bar chart visualizes the distribution of grade ranges (from 5.0-6.0 to above 9.0) across six student groups, showing how each grade category contributes to a total of 100% per student. The chart uses d3.stack() to create stacked segments, d3.scaleBand() for the categorical y-axis, and d3.scaleLinear() for the percentage x-axis. Hovering over a segment triggers a tooltip displaying the exact percentage for that grade range within the selected student group. Data is loaded from a CSV file and rendered as SVG elements.
