This stacked bar chart displays the average sepal and petal measurements for iris species from the provided CSV dataset. The visualization aggregates the raw data using `d3.nest()` and `d3.rollup()` to compute means per species, then renders four stacked segments per species using `d3.stack()`. Each segment’s height corresponds to its average measurement, with colors assigned via `d3.scaleOrdinal(d3.schemeCategory10)`. The chart uses D3 v5 with an SVG rendering approach, including axes generated through `d3.axisBottom()` and `d3.axisLeft()`.

A stacked horizontal bar chart displays the average sepal and petal measurements for iris species, segmented into three colored categories: setosa, versicolor, and virginica. The visualization uses D3.js v7 with an SVG renderer, mapping linear scales for the numeric average axis and a band scale for species categories. Each bar segment represents a species’ mean length or width, with interactive mouseover tooltips revealing exact percentage values. The chart includes axis labels, a title, and a color scale based on species, and the data is sourced from a local CSV file.

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.

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.

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.

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.

Activity6_Q2.3

This example displays a stacked bar chart of the Iris dataset, showing the cumulative contributions of sepal and petal measurements for each of the three species. It uses D3 v7 to load the CSV data with `d3.csv`, then applies the `d3.stack()` function to create series for the four attributes. The visualization renders as SVG, with axes and a legend constructed using `d3.axisBottom`, `d3.axisLeft`, and a custom legend group.

act_6_task2Q

This interactive visualization presents a stacked bar chart comparing average flower measurements across three Iris species. The bars display four features—sepal length, sepal width, petal length, and petal width—for each species, with a color-coded legend identifying each feature. Hovering over any segment reveals a tooltip with the specific average measurement in centimeters. The chart loads CSV data via `d3.csv` and uses `d3.scaleOrdinal`, `d3.scaleLinear`, and `d3.scaleBand` to position elements, while `d3.stack` computes the aggregated bar segments. The SVG rendering includes horizontal gridlines from `d3.axisBottom` and custom styling.

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.
