A line chart visualizes how average math scores change with hours of study, using a dataset of student scores from a CSV file. The x-axis represents hours of study, while the y-axis shows the average math score for each hour group, with data points marked by orange circles and connected by a blue line. Built with D3.js v7, the visualization loads `student_scores.csv`, aggregates scores using `d3.rollup` and `d3.mean`, and renders the chart as SVG with `d3.csv`, `d3.scaleLinear`, `d3.line`, and axis functions.

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`.

Assignment 7

This reusable D3.js scatter plot visualizes the relationship between math and physics scores for 40 students, with points colored by group membership. The chart uses `d3.csv` to load the dataset and custom scales via `d3.scaleLinear` for both axes and `d3.scaleOrdinal` for the categorical color encoding. The reusable function accepts parameters for data, axis value accessors, labels, dimensions, and title, rendering the chart as SVG with axes, labels, a legend, and semi-transparent circles. This design allows the same function to be applied to different datasets and attributes without modification.

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.

ice7_task2_2

This line chart visualizes the relationship between study hours and exam scores for a small dataset of students. The chart renders a smooth monotone curve through the data points, using blue dots to mark individual observations and a matching blue line to emphasize the overall trend. Built with D3.js v7, the visualization loads CSV data from a GitHub gist, applies linear scales with nice tick marks, and draws axes with labels. The tooltip functionality on hover is implemented but not fully connected in the visible code.

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.

Assignment 3

This visualization compares average screen time, sleep hours, and GPA across six student groups using a combined bar and line chart. Gray bars represent average screen hours, while blue, green, and red lines depict trends for screen time, sleep, and GPA, respectively. The chart uses D3’s `scaleBand` for categorical x-axes, `scaleLinear` for the y-axis, and `d3.line` to connect summary points. Data is loaded from a CSV via `d3.csv`, grouped into six slices, and aggregated with `d3.mean` to compute group averages.

ICE7-Q2b Line

A line chart shows the relationship between study hours and student scores, with a smooth curve indicating a positive trend. The visualization uses D3 v7 to load a CSV file, sort the data by hours, and render an SVG with linear scales for both axes. Gridlines and axis labels are generated using `d3.axisBottom` and `d3.axisLeft`, while the line path is drawn with `d3.line` and a monotone X curve to create smooth interpolation. The chart includes a title and axis labels, with data points from the `study_hours.csv` source.

activity 7.2

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`.
