This pie chart visualizes language usage distribution from a CSV file, with each slice colored by language and labeled interactively through a tooltip showing exact counts in millions. It uses D3.js v6’s `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate SVG paths with hover transitions, alongside a custom legend mapping the color domain. The chart loads data asynchronously via `d3.csv` and positions the pie off-center with a fixed radius, rendering static arcs with animated tooltip opacity changes.

Activity_7_Q1(11807290)

This chart visualizes the popularity of programming languages using a pie chart in D3 v7, with each slice colored via `d3.scaleOrdinal` and labeled with language names. It loads CSV data from a GitHub URL using `d3.csv`, then constructs the pie layout with `d3.pie` and renders arcs with `d3.arc`. A legend, dummy X and Y axis labels, and SVG rendering complete the static visualization.

Activity_7Q1_11807290

This pie chart visualizes programming language popularity using a dataset of user counts from a CSV file. It uses D3.js (v7) with its `pie` and `arc` APIs to generate the slices, which are colored via a category scale and rendered as SVG paths with stroke outlines. Labels are placed at each arc’s centroid, and a legend with colored rectangles is drawn on the left. The chart also includes dummy x- and y-axis labels, though these are not functionally linked to the data.

Activity7_Question1_1

This example shows a pie chart of programming language usage share percentages, with each category colored via a categorical color scale and labeled with its language name and percentage value. The visualization loads data from a CSV file using `d3.csv`, processes it with `d3.pie` and `d3.arc`, and renders the chart and a legend to SVG. Labels are placed outward from the arc centroids using `arcGenerator.centroid`, and the chart uses `d3.schemeCategory10` for distinct colors. The legend lists each language with its corresponding color and usage share, while the pie slices are semi-transparent with white stroke edges.

Activity7_Q1

This pie chart visualizes programming language usage by developers, with each language’s percentage labeled directly on its sector. The chart uses `d3.pie` and `d3.arc` to generate the SVG paths, while `d3.scaleOrdinal` assigns categorical colors. A legend on the right lists each language with its corresponding color and percentage value. Data is loaded as CSV from a GitHub gist, and percentages are formatted using `d3.format`. The SVG is fixed at 960×500 pixels, with the pie centered at (250, 250).

Assignment3.1

This pie chart visualizes the relative usage percentages of various programming languages from a remote CSV dataset. Rendered as SVG, the D3 v5 code constructs the chart using `pie()`, `arc()`, and `scaleOrdinal()`, with each slice labeled and a legend mapping colors to language names. The data is fetched via `csv()` from a GitHub gist.

Activity7.1

A pie chart displays the share of browser usage from a CSV dataset, with each slice labeled by its percentage. The chart uses D3 v7 to load CSV data asynchronously, applies `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` with the Tableau10 color scheme, and renders via SVG. A legend on the right maps color swatches to browser names, while slice texts show the corresponding usage values. The example demonstrates handling remote CSV data, SVG path generation, and legend construction with D3's `select` and `append` methods.

Activity7_Question1

This pie chart visualizes programming language usage by developers, with each slice sized by its percentage of the total. The chart uses D3 v5's `pie` and `arc` generators to create SVG paths, with `scaleOrdinal` assigning colors from a predefined array. Percentage labels are positioned using `arcGenerator.centroid`, and a legend displays language names and values. Data is loaded asynchronously via `d3.csv` from a GitHub gist, and the `format` function formats percentage values.

Activity7_Q1

This pie chart visualizes the percentage usage of programming languages among developers, with data fetched from a raw CSV file hosted on GitHub. The chart uses D3 v5’s `pie`, `arc`, and `scaleOrdinal` functions to generate colored slices and percentage labels, while a custom legend built with SVG `rect` and `text` elements lists each language and its corresponding value. The visualization is rendered as SVG, with colors assigned from a predefined array and formatted with `d3.format`.
