This example shows average student attendance for university modules as an animated bar chart, with hover interactions that highlight bars and display their precise values. The chart loads data from a CSV file and renders it as SVG using D3 v4. It uses `d3.scaleBand` and `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and transitions with `ease(d3.easeLinear)` to animate bar growth on load. Mouseover and mouseout handlers modify bar dimensions, add a temporary text label, and apply CSS classes for styling.

Average Attendance for each module

This visualization presents average attendance percentages for university courses, displayed as animated bar charts that grow sequentially upon load. Built with D3 v4, it uses `d3.scaleBand` and `d3.scaleLinear` to map course names and attendance values, with SVG rects transitioning via `transition.attr` and easing functions. Interactive mouseover and mouseout handlers alter bar width, position, and fill color between steelblue and orange while temporarily displaying the exact percentage value.

Average Attendance for each module

This D3.js v4 bar chart displays the average attendance percentage for each module, with bars animated sequentially on load. Hovering over a bar highlights it in orange, increases its size, and reveals the exact percentage value above it; moving the mouse away restores the original appearance. The visualization loads data from `attend_data.csv`, uses an SVG canvas, and leverages D3 scales for the band and linear axes, along with transitions for the hover effects.

Average Attendance for each module

This bar chart displays the average attendance percentage for each university module, using data from a CSV file. The visualization is built with D3.js v4 and renders as an SVG, with bars animating into place via a transition. Each module is labeled on the x-axis, while the y-axis shows percentages. Hovering over a bar triggers a mouseover event that highlights it in orange, enlarges it, and displays its exact value as a text label.

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.

Average Attendance for each module

This visualization shows the average attendance for each module using a bar chart, with the y-axis representing the percentage of attendance and the x-axis displaying different module codes. The bars animate as they grow to their final height, and hovering over a bar highlights it in orange and displays its exact attendance value as a text label. The code uses D3.js v4 APIs like `d3.scaleBand`, `d3.scaleLinear`, `d3.axisBottom`, and `d3.axisLeft`, along with SVG transitions for animation. The data is loaded from a CSV file containing course names, ages, and average marks.

d3 Updating Bar Chart With Dropdown

A bar chart displays the number of students per university module, with a dropdown menu to select a specific course. Selecting a new module triggers an animated transition that updates the bar heights and y-axis domain. The visualization is built with d3.v3, using SVG rectangles and the `transition` method for smooth updates, while the dropdown change event calls the update function. Data is loaded from a CSV file containing module codes and student counts.

Bar chart with D3.js

This bar chart visualizes the average marks for over one hundred university modules, ranked with the module name on the x-axis and the percentage score on the y-axis. The chart highlights a user’s hovered bar by dimming the hovered bar and displaying the percentage difference from it for all other bars via dynamically appended text elements. Built with D3.js v5, the visualization loads data from a CSV file using `d3.csv` and renders as an SVG with animated opacity transitions. Gridlines, a reference line, and axis labels are drawn using `d3.axisLeft` and `d3.axisBottom`.

SVG

This example shows student marks for individual modules, filtered by student ID through a dropdown menu. It presents a bar chart of marks per module for the selected student, with an animated update when the selection changes. The code uses D3 v5 to load the data with `d3.json`, binds the data to SVG rectangles, and renders axes with `d3.axisBottom` and `d3.axisLeft`. The x and y scales are created with `d3.scaleBand` and `d3.scaleLinear`, respectively. The visualization is a React project but uses vanilla JavaScript and SVG rendering for the chart.
