This example shows a simple pie chart for a categorical dataset with five categories (A–E), each represented by a colored slice with a value label. The chart is rendered as SVG using D3.js v6, with a legend displayed to the right of the pie. The code uses `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to compute slice geometry, apply colors from `d3.schemeCategory10`, and position the legend elements. Axis labels for categories and values are added manually, though no actual axes are present. The data is hardcoded as a sample array.

activity7, question1

This example shows a pie chart visualizing five categories (A–E) with their corresponding numeric values, alongside a color-coded legend and axis labels. It uses a static sample dataset defined in the code. The visualization is built with D3.js v6, using `d3.pie()` to compute arc angles and `d3.arc()` to generate SVG path data. A `d3.scaleOrdinal` with `d3.schemeCategory10` assigns colors, and the chart renders as SVG elements appended to the body.

This pie chart displays the distribution of three flower species from a loaded CSV dataset. The visualization uses d3.pie and d3.arc to compute and render the slices, with d3.scaleOrdinal providing categorical colors. Species names appear as labels positioned at each slice's centroid using arc.centroid, and the entire chart is drawn as SVG elements within a 500x500 viewport. The chart loads data through d3.csv from a remote gist URL and converts count values to numbers for proportional slice sizing.

Activity 7 Question 1

This example shows a classic pie chart built with D3.js, where each slice represents a category from a CSV dataset loaded remotely via `d3.csv`. The chart uses an ordinal color scale, and a legend lists each category alongside its subcategory. The code generates SVG paths with the `d3.arc` and `d3.pie` generators, and includes placeholder axis labels despite being a pie chart. The visualization renders entirely in SVG, with the legend placed to the right of the chart and a white stroke separating each slice.

This example visualizes delivery data as a pie chart, showing categorical proportions with labeled slices and a matching legend. Built with D3.js, it uses the pie and arc generators to compute slice geometry, scaleOrdinal with schemeCategory10 for colors, and SVG for rendering. The chart fetches its dataset from a GitHub-hosted CSV file and is implemented as a reusable piePlot component configured via chained methods for width, height, data, and field names.

Activity 7 Q1

This example shows a pie chart that visualizes categorical data loaded from a remote CSV file, with each slice colored using a categorical color scale and a legend pairing colors with category and subcategory labels. The chart is rendered as SVG using D3.js v6, where the `d3.pie()` generator computes slice angles and `d3.arc()` creates the path shapes. Data is fetched via `d3.csv`, and the color mapping uses `d3.scaleOrdinal` with `d3.schemeCategory10`. The code also adds axis labels (X and Y) that are not tied to the pie chart, acting as placeholders within the SVG layout.

Activity09 question1

This example shows a pie chart visualizing three categories (A, B, C) with their respective values (30, 20, 50) using a static SVG rendering. The chart is generated with D3.js v7, using the `d3.pie()` layout algorithm to compute arc segments and `d3.arc()` to draw the paths with an outer radius determined by the canvas dimensions. A legend maps each category to a color from the `d3.scaleOrdinal(d3.schemeCategory10)` palette. The code also includes text labels for the x-axis and y-axis, though the y-axis label references an undefined `margin` variable.

Activity9-Ques1

This example shows a basic pie chart visualization built with D3.js, displaying three categorical values from a hardcoded dataset. The chart renders as an SVG with colored arc segments using the `d3.pie` and `d3.arc` generators, with a categorical color scale (`d3.schemeCategory10`) mapping each category to a distinct hue. A legend on the right side labels each category, while x- and y-axis labels are added to the SVG container even though the pie chart itself does not use axes. The code also includes a link to a gist data source, though the dataset is defined inline.

Activity 7_question1

A pie chart displays categorical sales proportions, with each slice labeled and colored by category. Hovering over a slice reveals an HTML tooltip showing the percentage of total sales. The visualization is built with D3 version 7, using the `d3.pie()` layout and `d3.arc()` generator to create slice paths. It loads CSV data from a GitHub Gist via `d3.json()`, applies an ordinal color scale, and includes a custom legend. An SVG canvas renders all marks, while tooltip positioning tracks mouse coordinates.
