This example visualizes the percentage distribution of iris flower measurements (sepal length, sepal width, petal length, and petal width) across three species: setosa, versicolor, and virginica. It renders a stacked horizontal bar chart in SVG, with each bar representing a species and colored segments showing proportional contributions of each measurement type. The code uses d3.stack() to compute the stacked values, d3.scaleOrdinal() for color mapping, and d3.scaleLinear() and d3.scaleBand() for positioning. Interactive tooltips display precise percentage values on mouseover, with data loaded from the built-in Iris dataset.

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.

Activity 6 question 2

This visualization displays the percentage breakdown of four iris flower measurements (sepal length, sepal width, petal length, petal width) for each of the three iris species. Built with D3 v7, it uses a horizontal stacked bar chart where each bar represents a species, and colored segments show the proportional contribution of each measurement. The code employs `d3.stack` to compute the stacked data, `d3.scaleLinear` for the percentage axis, and `d3.scaleBand` for the categorical species axis. Interactive tooltips reveal exact percentage values on hover, while the SVG rendering uses `d3.select` and `d3.append` to construct the chart and handles.

Question2_Task2

A stacked bar chart visualizes the distribution of three iris species (setosa, versicolor, virginica) across sepal length values. The chart uses d3.csv to load the Iris dataset and d3.stack to create the stacked series, with d3.scaleOrdinal for color mapping. Each bar segment’s height represents the sepal width contribution per species, rendered as SVG rectangles via D3’s data joins and axis scales (d3.scaleBand, d3.scaleLinear). A legend identifies species colors.

Activity6_Question2

This stacked bar chart displays the percentage distribution of iris flower measurements (sepal length, sepal width, petal length, and petal width) across the three iris species. The visualization uses d3.v7 with d3.stack() to stack the percentage values for each species, d3.scaleBand for the categorical y-axis, and d3.scaleLinear for the percentage x-axis. A color scale maps each measurement type to a distinct color, and the chart includes hover interactions that display tooltips showing the exact percentage values for each segment.

Activity 6_Question 2

This stacked horizontal bar chart displays the percentage distribution of iris flower species, comparing the proportion of setosa, versicolor, and virginica flowers across different percentage ranges. The visualization uses D3.js v7 to render SVG elements, employing the d3.stack function to compute cumulative bar segments and d3.scaleOrdinal with a color scale to distinguish each species. Interactive tooltips appear on mouseover, revealing the exact percentage value for each segment. The data originates from the classic Iris dataset, with axes labeled for percentage and species categories.

Activity6_Task2 (question2)

This stacked bar chart visualizes the mean measurements of sepal length, sepal width, petal length, and petal width for three iris species: setosa, versicolor, and virginica. Each horizontal bar represents a species, segmented into colored sections corresponding to each measurement type, with tooltips displaying exact mean values on hover. The visualization loads data from iris.csv using D3 v7, applying a linear scale for the x-axis and a band scale for the y-axis. It employs `d3.stack()` to compute stacked bar segments, `d3.scaleOrdinal()` for color encoding, and renders all elements as SVG with interactive mouseover tooltips.

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.

Activity6_Task 2.1

This stacked bar chart displays the percentage distribution of four iris flower measurements—sepal length, sepal width, petal length, and petal width—across the three iris species in the classic iris dataset. The visualization uses D3 v7 to load and parse the CSV data, then renders the stacked bars in SVG using d3.stack() and d3.scaleBand() for the categorical species axis. A d3.scaleLinear() maps the percentage values, and mouseover interactions trigger tooltips showing exact percentages via d3.format().
