This visualization displays the Iris dataset as a stacked bar chart, breaking down sepal and petal measurements for each species. It uses D3 v6 functions `d3.csv`, `d3.stack`, `scaleBand`, and `scaleLinear` to aggregate and position the bars. The SVG output is rendered with `d3.select` and the `join` operator, while axes are drawn using `d3.axisBottom` and `d3.axisLeft`. A linear color scale maps attribute indices to a two-tone palette, distinguishing the four measurement categories.

question2.1

This visualization shows a stacked bar chart of the Iris dataset, displaying the total sepal and petal measurements for each species. The chart uses d3.stack() to aggregate the four numerical attributes into color-coded segments per species, with a tooltip showing individual segment values on hover. The visualization renders with SVG, using d3.scaleOrdinal for colors, d3.scaleBand for the species axis, and d3.scaleLinear for the measurement axis. A legend identifies each attribute, and the data is loaded from an external CSV file using d3.csv.

question2

This stacked bar chart visualizes the Iris dataset, showing the average measurements of sepal length, sepal width, petal length, and petal width for three Iris species: setosa, versicolor, and virginica. Using D3.js v7, the visualization applies `d3.stack()` to arrange the four numerical attributes as stacked segments within each species category. The code uses scale bands and linear scales for positioning, with color encoding via `d3.scaleOrdinal` and the Category10 color scheme. The resulting SVG provides a compact comparison of the relative contributions of each measurement type across species.

Activity-8_Question-2

This example visualizes the Iris dataset as a stacked bar chart, showing the relative contributions of sepal length, sepal width, petal length, and petal width for each of the three species. It uses d3.csv to load the data and d3.stack to transform the four numeric columns into stacked series. The chart renders as SVG with d3.scaleBand and d3.scaleLinear axes, and includes an interactive hover effect that increases bar opacity. A color-coded legend identifies each measurement category.

Activity6Question2

This stacked bar chart visualizes the Iris dataset, showing the average measurements of sepal length, sepal width, petal length, and petal width for each of the three iris species. The code uses d3.csv to load the data, d3.stack to group the four numeric attributes into layers, and d3.scaleBand and d3.scaleLinear to map species and cumulative values. Rendered as SVG, each colored segment represents one measurement category, with axes added via d3.axisBottom and d3.axisLeft.

question 2

This stacked bar chart visualizes the proportion of sepal length and sepal width measurements across three iris species, demonstrating how these attributes vary by category. Each species is represented as a full-height bar segmented into two colored sections, with the y-axis showing the summed measurement values. The visualization uses d3.stack() to construct the stacked series and d3.scaleBand with d3.scaleLinear for positioning. Hovering over any segment triggers a tooltip displaying the species and exact value, while d3.axisLeft and d3.axisBottom label the axes. Data comes from the included CSV file.

Task2_Question

This example visualizes the Iris dataset as a stacked bar chart, where each bar represents one of the three iris species and is divided into segments corresponding to sepal length, sepal width, petal length, and petal width. The chart uses D3 v7 to load the data from a CSV file, stack the four measurement categories, and render them as color-coded rectangles on an SVG canvas. The code demonstrates d3.csv for data loading, d3.scaleBand for the x-axis, d3.scaleLinear for the y-axis, d3.scaleOrdinal for colors, and d3.stack for computing the stacked segments.

Activity6_Question3

This stacked bar chart visualizes the average sepal and petal measurements for three Iris species (setosa, versicolor, virginica) using D3.js v7. It shows how each species’ total measurement is composed of four attributes, as aggregated from the provided iris.csv data. The visualization uses d3.stack for data transformation, d3.scaleBand and d3.scaleLinear for positioning, and renders via SVG. A color-coded legend identifies each variable, and the d3.axisBottom and d3.axisLeft functions create the labeled axes.

Activity6_Question2

This visualization shows the average measurements of sepal and petal dimensions for three Iris species as a stacked bar chart, using a subset of the classic Iris dataset. The chart aggregates 150 data points into three bars, one per species, with each bar divided into four colored segments representing the mean sepal length, sepal width, petal length, and petal width. The visualization is rendered using D3.js v7, with the `d3.stack()` API to create the stacked layout and `d3.axisBottom` and `d3.axisLeft` for the axes. A legend identifies the color encoding for each measurement, while white strokes separate the stacked segments.
