This example shows a horizontal bar chart comparing marks across grade categories (Grade_A through Grade_F) using a CSV data source. Each bar is color-coded based on its mark value via the `colourPicker` function, and hovering with the mouse triggers an animated enlargement of the bar while displaying a tooltip with the mark and grade. The visualization uses D3 v4 with SVG rendering, `d3.scaleLinear` for the x-axis, `d3.scaleBand` for the y-axis, and transitions via `transition.duration` and `transition.delay` for the initial render and hover interactions.

This visualization shows the average grade for each module as a bar chart. The bars are colored steel blue and transition sequentially into place. Hovering over a bar highlights it in orange, temporarily expands it, and displays a label with the corresponding mark. The code uses d3.csv to load module data and d3.scaleBand with d3.scaleLinear to map the axes, while d3 transitions add animation to the initial render and hover interactions.

Untitled

This bar chart displays the number of students for various grades and locations, with bars colored blue and axes labeled "Grades" and "Num_students." The visualization uses D3.js v6 to create an SVG rendering, employing `d3.scaleBand` for the categorical x-axis and `d3.scaleLinear` for the numeric y-axis. Data is hardcoded in an array of objects, while axes are generated with `d3.axisLeft` and `d3.axisBottom`. The chart includes a pink background rectangle and console logs for debugging scale behavior.

Untitled

This example shows the distribution of student counts across letter grades, with horizontal bars colored in a solid blue tone. The chart uses D3.js v6 to construct an SVG visualization, employing `d3.scaleLinear` for the x-axis and `d3.scaleBand` for the categorical y-axis. It renders rectangles whose widths are proportional to `num_students` values, with axes generated via `d3.axisLeft` and `d3.axisBottom`. The data is hardcoded in the script rather than loaded from the available CSV file.

This example shows a grouped bar chart comparing values across three categories for multiple groups, with each category represented by a colored bar. The visualization uses D3.js v4 to load data from a remote CSV file, which is parsed with `d3.csv`. Bars are rendered as SVG rectangles, with an ordinal color scale mapping categories to red, blue, and green. The X-axis uses `d3.scaleBand` for group positioning, while a nested subgroup scale positions bars within each group, and a linear scale maps values to the Y-axis.

Untitled

This example shows a 3D bar chart with five categories (A–E) and values from 10 to 50, rendered as skewed, prism-like paths using D3 v5 and the d3-3d plugin. It uses `d3.scaleBand` for the x-axis, `d3.scaleLinear` for the y-axis and depth, and builds each bar’s SVG path manually with 3D coordinates. Hovering over a bar reveals its value in a tooltip, and clicking toggles a selected state, though the fill change is incomplete.

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.

Untitled

This example presents a bar chart of average marks for university modules, with each bar representing a module code. The chart uses D3 v4 within a React framework to render SVG elements. Bars animate in sequentially using a transition with linear easing, and hovering over a bar triggers a mouseover event that highlights it in green, expands its width, and displays its average mark as a label. A mouseout event restores the bar’s original style and removes the label. The data comes from a CSV file containing module codes, student counts, and average marks.

Untitled

A bar chart displays categorical data with drop-shadowed rectangles, using D3 v2 to map values to an ordinal x-scale and linear y-scale. The visualization animates via SVG transitions, with tick labels formatted from a caption mapping. It relies on jQuery for container sizing and D3’s `d3.svg.axis` for axes, rendering inside an HTML div with a filter-defined shadow effect.
