This area chart shows the average exam score for each number of hours studied, using data from a CSV file of student performance factors. The visualization aggregates the raw data with `d3.rollups`, computing the mean score per hour, and then renders an orange, semi-transparent filled area with a dark orange stroke using D3's `d3.area` and `d3.line` generators. Axis scales are set with `d3.scaleLinear` and rendered via `d3.axisBottom` and `d3.axisLeft`, producing an SVG output.

q3

This line chart visualizes the relationship between hours studied and average exam scores, using data from a CSV file on student performance factors. The visualization aggregates the data with `d3.rollups` and `d3.mean` to calculate average scores per hour, then sorts the results. Rendered in SVG, it draws a green line using `d3.line` with circular data points, and employs `d3.scaleLinear` for axes and `d3.axisBottom`/`d3.axisLeft` for tick marks. The chart includes labeled axes for both variables.

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.

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.

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`.

Assignment 7-Part 4- Area chart

This area chart visualizes the relationship between hours of study and average math scores, showing a clear positive trend. The D3.js visualization uses `d3.csv` to load the student_scores.csv dataset, then employs `d3.rollup` to group the data by study hours and calculate the mean math score using `d3.mean`. The chart is rendered as an SVG using `d3.area` to create the filled region, with blue fill and stroke, orange circles marking individual data points, and axes created via `d3.axisBottom` and `d3.axisLeft`. The visualization includes labeled axes and a title, with scales defined by `d3.scaleLinear` and domain adjustments using `d3.extent` and `d3.max`.

Ice6 q2

This scatter plot visualizes the relationship between hours studied and exam scores using a dataset of student performance factors from a GitHub-hosted CSV file. It shows individual data points as orange, semi-transparent circles, with hours studied on the x-axis and exam scores on the y-axis. The visualization is built with D3 v7, using `d3.csv` to load the data, `d3.scaleLinear` for both axes, and `d3.axisBottom` and `d3.axisLeft` for tick marks. The chart is rendered as an SVG, with circles positioned using the mapped coordinates.

ice7_task3

This area chart visualizes the relationship between hours studied and exam scores from a `studentscores.csv` dataset. The blue area shape, with a monotone-x curve, shows a general upward trend where more study hours correspond to higher exam performance. The visualization is built with D3 v7, using `d3.csv` to load data, `d3.scaleLinear` for axes, `d3.axisBottom` and `d3.axisLeft` for ticks, and `d3.area` with `d3.curveMonotoneX` to render the smooth area. Data points are marked with dots, and a tooltip is implemented for interaction.

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.
