This example shows a stacked horizontal bar chart of student performance levels across five subjects, with each bar divided into percentages of Excellent, Good, Average, Below Average, and Poor ratings. The visualization uses d3.stack to compute the stacked series, d3.scaleBand for the subject categories, and d3.scaleLinear with a custom color palette to encode the performance categories. Interactive tooltips appears on hover to display exact percentages, while a legend identifies each performance level. The data comes from a CSV file loaded locally, and the chart is rendered as an SVG with D3 v7.

Activity-6-Question-2

A stacked bar chart shows the percentage of student ratings across six subjects, with each bar segmented into five rating bands from "below 60%" to "above 90%". The chart uses `d3.stack()` to compute the layered data and `d3.scaleOrdinal()` for color encoding. Interactive tooltips appear on mouseover, displaying the exact percentage for each segment. The visualization is rendered as an SVG with axes created via `d3.axisLeft()` and `d3.axisBottom()`, reading data from a local CSV file.

Fork of Activity6_Question 2

This stacked bar chart visualizes the distribution of performance ratings across six academic subjects, using data from a CSV file. Each bar is segmented into five percentage ranges, from below 60% to above 90%, with colors mapping to each category. Built with D3 v7, the visualization uses `d3.stack()` to create the stacked series, `d3.scaleBand()` and `d3.scaleLinear()` for axes, and an SVG renderer. Interactive tooltips display exact percentage values on mouseover, while a legend identifies the rating categories.

Activity6_Question2.3

This example presents a stacked horizontal bar chart that visualizes the distribution of grade percentage ranges (e.g., Below 60%, 60%-70%) across various academic subjects. Each bar is segmented by color-coded rating categories, with the width of each segment representing the proportion of ratings in that category. The visualization uses D3.js v7, employing `d3.stack()` for data restructuring, `d3.scaleBand()` for the categorical y-axis, and `d3.axisBottom()` for the continuous x-axis. Hovering over a segment reveals a tooltip with the exact percentage for that subject and rating band. Data comes from a CSV file.

Activity6task2-q1

This stacked bar chart visualizes the distribution of score ranges across six school subjects, revealing how grade percentages vary by subject. Each horizontal bar represents a subject, segmented into seven color-coded score intervals from “below 40” to “above 90.” Built with D3 v7 and SVG, the chart uses `d3.stack()` to compute stacked segments and `d3.scaleOrdinal` for color mapping. Hovering over a segment displays a tooltip showing the exact percentage for that score range within the subject. The data comes from a CSV file containing percentage values that sum to 1 for each subject.

activity6_task2

A stacked horizontal bar chart displays customer satisfaction ratings across five product categories, with segments representing the percentage of responses in each rating level from "Excellent" to "Very Poor." The visualization uses D3 v7 with SVG rendering, employing `d3.stack()` to compute stacked series, `d3.scaleLinear` for the x-axis, `d3.scaleBand` for product categories, and `d3.scaleOrdinal` for color mapping. Interactive tooltips appear on mouseover, showing the exact percentage for each rating segment. Data comes from a local CSV file loaded asynchronously.

activity_6 question2

This example presents a stacked horizontal bar chart that visualizes the distribution of low, moderate, and excellent product ratings as percentages, with each bar segment representing a rating category. The chart uses D3 v7's stack, scaleLinear, scaleBand, and axisBottom APIs to construct the visualization from a local CSV file. Interactive tooltips display the exact percentage of each rating when hovering over a segment, achieved through event listeners that calculate the value from the underlying data. SVG rendering handles the output, and the chart is enhanced with custom styling from an external stylesheet.

Activity6_Q3

This stacked bar chart visualizes the percentage distribution of grades (A, B, C, D) across five school subjects, with each bar segment color-coded by grade category. The chart uses `d3.csv` to load the data, `d3.stack` to compute cumulative values, and `d3.scaleBand` with `d3.scaleLinear` to map subjects and percentages. Hovering over a segment reveals a tooltip showing the grade and its percentage. SVG rectangles are rendered using D3's `selectAll` and `join` operations, with axes and labels drawn via `d3.axisLeft` and `d3.axisBottom`.

activity-6-a-2

A stacked bar chart shows the distribution of food ratings across five categories, from "Below 5.0" to "Above 8.5," for six food items. Each bar segment’s length encodes the proportion of ratings, with hover interactions displaying exact percentages via a tooltip. The visualization uses D3 v7’s `d3.stack`, `d3.scaleOrdinal`, `d3.scaleLinear`, and `d3.scaleBand` to render SVG rectangles, with data loaded from a CSV file and a custom color scale mapping each rating category.
