A bar chart displays the grades of 100 individual students, with each bar color-coded by letter grade category from A (green) through E (red). The chart uses an ordinal color scale and a linear grade axis from 0 to 100, with student names rotated along the bottom axis. An interactive tooltip shows the student name, numeric grade, and category on hover. The code loads data from a local CSV file using `d3.csv` and builds the visualization with D3’s band and linear scales, axes, and tooltips, rendered as an SVG.

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.

A bar chart displays average marks per subject, computed from a CSV dataset of student scores. The visualization uses D3.js v6 to load the data, calculate averages with `d3.mean`, and render SVG rectangles scaled by `d3.scaleBand` and `d3.scaleLinear`. Axes are added via `d3.axisBottom` and `d3.axisLeft`, with labels and a title. Bars turn orange on hover through CSS, and the chart includes rotated x-axis tick labels and clear axis annotations.

This bar chart displays the value of each category, sorted in descending order. Built with D3 v7, it loads data from a CSV file via a Gist URL using `d3.csv` and `d3.autoType`. The visualization uses a band scale for categories, a linear scale for values, grid lines, rotated axis labels, and a tooltip that appears on mouseover.

Fork of Fork of Student Scores Bar Char

This horizontal bar chart displays student scores from a CSV file, with each student’s name on the y-axis and their score on the x-axis from 0 to 100. Purple rectangles represent the scores, and hovering over a bar reduces its opacity. The visualization uses D3 v5 with `d3.csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to load data and render the SVG. The chart is titled “Bar Chart of Student Scores” and includes labeled axes with a fixed margin layout.

Fork of Bar chart

A horizontal bar chart displays the average grade achieved for a list of university module codes, sorted by grading scale. The visualization emphasizes the distribution of marks across many modules, using a color gradient from steelblue to grey to represent low to high scores. Built with D3 v5, it uses `scaleLinear` for the x-axis and color scale, `scaleBand` for y-axis categories, and `axisBottom` with custom tick formatting. SVG rectangles render the bars with `transition` animation over a duration of 1000ms, transitioning their width and fill. The data is loaded from a CSV file via `csv` and parsed for numeric marks.

This bar chart displays categorical values from a remote CSV file hosted on GitHub. The visualization uses D3.js v7 to load the data with `d3.csv` and renders it as an SVG. The chart's y-axis is scaled linearly with `d3.scaleLinear` and includes nice tick marks, while the x-axis uses `d3.scaleBand` for categorical spacing. The code appends steelblue rectangles, rotates x-axis labels, and adds a title, with margins and axes positioned via SVG transforms.

Fork of Student Scores Bar Chart

This horizontal bar chart displays student exam scores from a CSV file, with each bar representing an individual student’s score on a scale from 0 to 100. The visualization uses D3 v5’s `csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to load the data and render an SVG with purple bars that become semi-transparent on hover. Student names appear on the y-axis, while the x-axis shows score values, with the chart laid out within a 960-by-450-pixel SVG canvas.

Fork of Making a Bar Chart 3

This bar chart visualizes student test marks, with each bar’s length representing a score from 1 to 100. Built with D3 v5, it uses `d3.scaleLinear` for the x-axis, `d3.scaleBand` for categorical student labels, and `d3.axisBottom` with a custom tick formatter that abbreviates numbers. The SVG renders steel-blue rectangles, and the chart includes axis labels and a title. Data is loaded from a CSV and multiplied by 1,000 during preprocessing.
