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.

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.

This bar chart displays student scores from a CSV file, using a horizontal layout with student names on the y-axis and score values from 0 to 100 on the x-axis. The visualization uses d3.csv to load the data, d3.scaleBand for the categorical axis, d3.scaleLinear for the numeric scale, and d3.axisLeft and d3.axisBottom to render the axes. Each rectangle’s width is proportional to the score, with a purple fill and hover effect that reduces opacity. The chart is rendered as SVG within a 960×450 pixel viewport, with margins applied to position the plot area.

This visualization summarizes student and sports data from a CSV file, displaying key statistics such as total student count, unique favorite subjects, and the top team. It presents these findings in a simple SVG bar chart that shows team counts, with axes labeled using D3's `d3.axisBottom` and `d3.axisLeft`. The data is loaded via `d3.csv` and processed using `d3.rollups` and `d3.scaleBand`, resulting in an accessible chart with a summary section and rotated x-axis labels for readability.

This bar chart displays student test scores from a CSV file, ranking each student along the y-axis with a score from 0 to 100 on the x-axis. The purple bars are rendered as SVG rectangles within a fixed 960 by 450 pixel canvas, using D3 v5’s `scaleLinear` and `scaleBand` to map data to coordinates. The chart includes axes generated by `axisLeft` and `axisBottom`, with a hover effect that reduces bar opacity. The student data is loaded asynchronously from `data.csv`.

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 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.

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.
