This visualization uses an area chart to show the relationship between study hours and the corresponding grade values (A=4, B=3, C=2, D=1) for individual students. The chart’s fill uses a linear gradient transitioning from rose to blue to green. The code loads a CSV from GitHub, filters for entries with study hours and grades, maps letters to numeric values, and sorts the data by study hours before creating a smooth monotone-X curve. The axes are drawn with `d3.axisBottom` and `d3.axisLeft`.

ice7_task3

This area chart displays the relationship between hours studied and average exam scores, using a steelblue fill with orange data points to highlight the trend. The visualization groups individual student records by rounded study hours and computes the mean exam score for each group. Built with D3 v7, the chart uses `d3.csv` for data loading, `d3.groups` to aggregate the data, `d3.scaleLinear` for axis scaling, and SVG rendering with animated elements and interactive tooltips on hover.

Activity6_Question6

This scatter plot visualizes the relationship between hours studied and exam scores for students, with data points colored by gender (blue for male, pink for female). It uses d3.csv to load the dataset from a GitHub URL, d3.scaleLinear to map data values to pixel coordinates, and d3.axisBottom and d3.axisLeft to render axes. The SVG chart includes a legend and displays axis labels for both variables.

Activity6_Q3

This stacked bar chart visualizes the percentage distribution of grades (A, B, C, D) across five school subjects, with each bar segment color-coded by grade category. The chart uses `d3.csv` to load the data, `d3.stack` to compute cumulative values, and `d3.scaleBand` with `d3.scaleLinear` to map subjects and percentages. Hovering over a segment reveals a tooltip showing the grade and its percentage. SVG rectangles are rendered using D3's `selectAll` and `join` operations, with axes and labels drawn via `d3.axisLeft` and `d3.axisBottom`.

Activity 6 Question 4

A bubble chart of student scores maps math and reading performance for ten students, with circles sized by weekly study hours. The visualization encodes each student’s test results as x- and y-coordinates, while a square-root scale sets bubble radius to reflect study time, enabling quick comparison of academic achievement and effort. Built with D3 v7, the chart uses `d3.scaleLinear` for axes, `d3.scaleSqrt` for bubble sizing, and `d3.axisBottom` and `d3.axisLeft` to render scales. Interactive hover tooltips, implemented with D3 event listeners and a styled HTML division, display each student’s name, scores, and study hours. Data comes from the included CSV file, and the SVG rendering includes explicit margin and transform logic.

Fork of D3 Starter - ice 7 - scatter plot

This scatter plot visualizes the relationship between study hours and exam scores for 120 students, with each point colored by category (A–D) and a legend mapping colors to these groups. The D3 v7 code loads data from a CSV file, converts the numeric columns, and uses `d3.csv`, `d3.scaleLinear`, `d3.scaleOrdinal`, and `d3.axisBottom`/`d3.axisLeft` to render the SVG chart. Axes are labeled, and the plot uses a built-in color scheme (`d3.schemeSet2`).

AREA PLOT

This area plot visualizes average study hours by age, showing the range between minimum and maximum study hours for each age group in light blue. The chart uses D3.js v7 to load CSV data from a remote gist, group records by age, and compute summary statistics including mean, min, and max study hours. The code employs `d3.area()` to generate the filled region between the min and max values, with `d3.scaleLinear` axes and an SVG-based legend. The data is fetched asynchronously via `d3.csv()` and rendered within an 800×400 pixel SVG container.

Fork of question678

This scatter plot visualizes the relationship between study hours and exam scores for a group of students, using data from a CSV file. Each circle represents a student, positioned by study hours on the x-axis and exam score on the y-axis, with colors assigned via `d3.scaleOrdinal` based on student ID. The visualization uses D3.js v7 to render an SVG, drawing circles and axes with `d3.axisBottom` and `d3.axisLeft`, and labels for each axis.

A4_ScatterPlot

This example visualizes the relationship between study hours and exam scores using a scatter plot, where each circle represents a student. The data comes from a CSV file loaded with D3’s `d3.csv` method and filtered to exclude zero-value pairs. The SVG chart uses `d3.scaleLinear` for both axes, `d3.axisBottom`, and `d3.axisLeft` for tick marks, while circles are appended with `d3.selectAll` and `enter`. Interactive tooltips appear on mouseover, displaying the exact hours and scores for each point. All rendering is done with React-compatible vanilla JavaScript and D3 v6.
