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.

area q4

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.

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`.

ice6 q3

A combined bar chart and line chart visualize the relationship between student attendance (bars) and exam scores (line) across hours studied, using the first 50 rows of the StudentPerformanceFactors dataset loaded via `d3.csv`. The SVG rendering uses `scaleBand` for the x-axis, `scaleLinear` for the y-axis, and `d3.axisBottom`/`axisLeft` for ticks. Attendance bars and a red exam-score line are generated with `selectAll` and `d3.line`, while a static legend clarifies the two encodings.

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.

Q3 D3 combined chart Dinesh

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.

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.

Ice_task2_2

This interactive line chart shows the relationship between hours studied and average exam score, aggregating individual student records into rounded hourly bins and plotting the mean score for each bin as a connected line with orange data points. Hovering over a point reveals a tooltip with the exact values. The visualization is built with D3 v7, using `d3.csv` to load the dataset, `d3.groups` and `d3.mean` for aggregation, and `d3.scaleLinear` with `d3.axisBottom` and `d3.axisLeft` for the coordinate system. It renders as SVG with animated transitions, styled with CSS for a clean card-based layout.
