This multi-line chart displays the average first-semester grade by age at enrollment, with separate lines for male and female students. The visualization uses D3.js v7 to load the dataset via `d3.csv`, clean and aggregate the data with `d3.rollups` and `d3.mean`, and render the chart as an SVG. Points along each line include interactive tooltips showing gender, age, and average grade. Axes are generated with `d3.axisBottom` and `d3.axisLeft`, and a legend distinguishes the two gender groups.

Visualization6D3.js

This scatter plot visualizes the relationship between student age at enrollment and first-semester grade, with points colored according to gender and retention status (retained versus dropped). Each dot encodes a single student record from the dataset, and hovering reveals precise age, grade, and gender values through a tooltip. The visualization uses D3 v7 with SVG rendering, employing `d3.scaleLinear` for the x and y axes, `d3.scaleOrdinal` for categorical coloring, and `d3.axisBottom` and `d3.axisLeft` for the coordinate system. A static HTML legend outside the SVG explains the four color-coded groups.

phase2Visualization3

This example presents a static D3.js (v7) SVG scatter plot that visualizes the relationship between a student's age at enrollment and their first-semester grade, with data points colored by retention status (Retained, Dropped, or Enrolled). The visualization uses the `d3.csv` data loading API to read the dataset and the `d3.scaleLinear` and `d3.scaleOrdinal` functions to map age and grade to x/y coordinates and retention status to color. Hovering over a circle triggers a mouseover event that uses the `d3.select` API to show a tooltip with the exact age, grade, and status values. The chart includes labeled x- and y-axes ('Age at Enrollment' and '1st Semester Grade') generated using the `d3.axisBottom` and `d3.axisLeft` APIs.

phase2Visualization1D3js-Retention by age

This chart shows the total number of students grouped by gender, with blue bars for males and red bars for females. It uses the d3.csv method to load the dataset, then d3.rollups to count occurrences per gender before mapping values to bars. The visualization is rendered as SVG, with d3.scaleBand and d3.scaleLinear for positioning, plus interactive tooltips triggered by mouseover events. Data comes from the provided dataset.csv file, which includes academic and demographic records.

visualization8D3.js

This example visualizes the relationship between inflation rate and average first-semester grades, using a line chart with circular markers. The visualization aggregates data from a CSV file by grouping student records by inflation rate and calculating the mean grade for each group. Built with D3.js v7 and rendered as an SVG, it uses `d3.csv` for loading data, `d3.rollups` for aggregation, and `d3.line` for the path. Interactive tooltips appear on hover, displaying the exact inflation rate and average grade for each point.

areachart

This area chart visualizes average depression levels across letter grades A through F, split by male and female students. The data comes from a CSV file loaded via `d3.csv` and is aggregated with `d3.mean` for each gender and grade combination. Rendered as SVG using `d3.area` with a monotone curve, the chart also includes tooltips on circles for precise values, axis labels, and a legend. Color encoding distinguishes genders through `d3.scaleOrdinal`, with hover interactions managed by event listeners.

sample 3

Two side-by-side donut charts show grade distribution (A–F) for male and female students, with a tooltip revealing count, depression level, and percentage for each grade. The visualization uses D3 v7’s `d3.pie`, `d3.arc`, and `.join` to render SVG paths and labels. Hovering expands a slice via `arcHover` while an HTML tooltip follows the cursor. Data is hardcoded in JavaScript arrays, and a horizontal legend maps grades to a categorical color scale.

visualization9d3

This stacked bar chart displays the count of students by their final academic outcome (Dropout, Graduate, or Enrolled), with each bar segmented by gender (Male or Female). The visualization uses D3 v7 to load CSV data via `d3.csv`, aggregate counts, and render SVG rectangles through `d3.stack` and `d3.scaleBand`. Interactive tooltips appear on mouseover, showing the exact count per gender and outcome. The chart includes axes labeled “Target Outcome” and “Number of Students,” with a categorical color scale assigning blue to males and orange to females.

question 2

This example shows a chart that uses an area path to compare average math scores between male and female students, with the D3 area generator mapping gender categories along the x-axis and score values along the y-axis. The visualization loads student performance data from a hosted CSV file, aggregates the math scores by gender using `d3.rollup`, and renders the result as an SVG area chart with labeled axes. The code applies D3 v7 scales, axes, and generators like `d3.area`, `scaleBand`, and `scaleLinear` to construct the figure.
