This combined chart visualizes 200 weeks of student performance data, showing study hours as blue bars, sleep hours as a dashed green line, and exam scores as a red line across a shared timeline. The visualization uses two distinct y-axes—a left axis for hours and a right axis for exam scores—to accommodate the different measurement scales. Built with D3 v7, the chart employs `scaleBand`, `scaleLinear`, `d3.line` with `curveMonotoneX`, and `d3.axisLeft`/`d3.axisRight` to render the SVG elements, including custom gridlines and a legend.

Q3 D3 Starter - Dinesh

This example displays a multi-series line chart tracking student performance across 200 weeks, plotting study hours, sleep hours, and exam scores on a single y-axis. The D3 v7 code loads data from a CSV file and uses `d3.line` with `curveMonotoneX` to generate smooth paths for each metric, with circles marking individual data points. Axes and gridlines are rendered via `d3.axisLeft` and `d3.axisBottom`, while a legend distinguishes the three colored series. The visualization employs an SVG-based rendering approach with a white background and styled grid lines.

Q2 D3

A scatter plot visualizes the relationship between hours studied and exam scores across 150 students, using D3 v7 to load CSV data and render SVG circles mapped through linear scales. The chart includes labeled axes, a bold title, and semi-transparent steelblue points sized at 4 pixels. Data comes from a local `study_scores.csv` file, with axes and scales configured via `d3.scaleLinear`, `d3.extent`, and `axisBottom`/`axisLeft`.

Combined Chart

This combined chart displays average study hours as bars and average exam scores as a line, grouped by sleep-hour bins. It uses `d3.rollups` to aggregate the CSV data and a dual-axis layout with an SVG render. The chart is built with D3 v7, featuring flexible column detection and dark-themed styling.

Multi-Series Line Chart

This multi-series line chart examines the relationships between study hours, sleep hours, and exam scores for 187 students. The visualization displays three trends on a shared axis, with each series represented by a distinct color. Built with D3.js v7 and rendered as an SVG, the code uses `d3.text` and `d3.dsvFormat` to efficiently parse the comma-delimited CSV data file. The chart automatically detects column names and scales, providing a clean overview of how these academic factors correlate with performance.

activity7.1q2

This example shows the relationship between hours studied and exam scores using an area chart, with a light blue filled region and steel blue outline. It loads student performance data from a GitHub-hosted CSV file and parses the numeric columns. The visualization uses D3 v6 to create linear scales for both axes, an `area` generator for the filled path, and `axisBottom` and `axisLeft` for the axes. Labels are added for both dimensions, and the SVG is rendered directly into the page.

Fork of D3 Starter - vijq3

This area chart shows the relationship between study hours and exam scores for 120 students. The filled region, rendered using the `d3.area()` generator with a monotone-x curve, emphasizes the magnitude of exam scores as study hours increase. Individual data points appear as blue circles with interactive tooltips. Data from the CSV file is plotted using `d3.scaleLinear` for both axes and the SVG rendering framework.

line chart Ice_7

This line chart shows the exam scores of ten students alongside their study hours, with each score point rendered as a distinct shape that changes by score range: triangles for scores under 60, diamonds for scores between 60 and 80, and crosses for scores above 80. The line itself uses a vertical gradient stroke, transitioning from green at lower scores to red at higher scores, with a dashed pattern. Built with D3 v7, the code employs `d3.scalePoint`, `d3.line`, `d3.axisBottom`, `d3.axisLeft`, and `d3.symbol` with triangle, diamond, and cross generators, all rendered as SVG elements.

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.
