This pie chart shows the distribution of cars by cylinder count in the CarPerformance dataset. The visualization groups entries by cylinder type and maps the resulting counts to pie arc sizes, with each segment labeled by its cylinder category. It uses D3 v7 APIs including `rollups` for aggregation, `pie` and `arc` for generating the chart geometry, and `scaleOrdinal` for color encoding. A legend identifies the color-to-cylinder mapping, and the data is loaded and parsed via D3's `csv` function from a GitHub-hosted CSV file.

CarPerformance PieChart

This pie chart visualizes how vehicles in the CarPerformance dataset are distributed across three horsepower ranges: low (≤120 HP), medium (121–160 HP), and high (>160 HP). Each slice’s size reflects the count of vehicles in that category, with colored segments and a legend for identification. The visualization loads data from a CSV file using `d3.csv`, then applies `d3.pie` and `d3.arc` generators to create the slices. A `d3.scaleOrdinal` color scale maps the categories to distinct colors, while `arcGen.centroid` positions the labels within each slice.

Pie chart ice 7

A pie chart shows the distribution of cars by cylinder count, sourced from the Auto MPG dataset. Each slice is labeled directly with its category and percentage, while a legend on the right lists raw counts. The chart uses D3 v7 modules `csv`, `rollup`, `pie`, `arc`, and `scaleOrdinal` with `schemeTableau10`, rendering slices and labels as SVG elements within an 880 by 520 pixel viewport.

Q1_DataViz_PiechartForCarPerformance

This pie chart displays the distribution of horsepower across various car manufacturers. The visualization uses a D3.js pie chart to represent each model's contribution to total horsepower, with percentage labels displayed directly on the slices. A legend maps colors to car models, while the chart includes axis labels for context. The implementation uses d3.pie for slice calculation, d3.arc for path generation, and d3.scaleOrdinal with d3.schemeCategory10 for color assignment. Data is loaded from a remote CSV file and rendered as SVG within a web page.

Pie Chart

A pie chart displays automobile sales proportions for different car brands, with each slice labeled by percentage and accompanied by a legend showing brand names and their corresponding sales shares. The visualization uses D3 v5’s `pie` and `arc` generators to compute slice angles and paths, with `scaleOrdinal` assigning colors from a predefined palette. Data is loaded as CSV from a GitHub repository, and the chart renders as SVG with custom styled text and legends.

Pie Chart

A pie chart built with D3 v7 displays the distribution of car types from a CSV file hosted on a GitHub Gist. The visualization aggregates raw records into categorical counts by type—Sedan, SUV, Truck, and Coupe—and shows each segment's percentage share using `d3.scaleOrdinal` with the `d3.schemeSet2` palette. D3's `arc` generator positions slices, while leader lines and external labels annotate each wedge. An interactive legend, populated via the `d3.select` API, highlights corresponding slices on hover, and a tooltip provides additional detail. The chart uses SVG rendering.

Fork of Q1_DataViz_PiechartForCarPerformance

This example shows the distribution of horsepower across various car models using a pie chart with a color-coded legend. It loads CSV data from a GitHub gist via `d3.csv`, then builds the chart with `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` using `d3.schemeCategory10`. The SVG renders labeled arcs with model and horsepower values, while a separate legend group lists each model. The code uses D3 v6 and renders entirely as SVG within a dedicated container.

Fork of D3 Starter -(pie chart)

This pie chart visualizes the distribution of car horsepower into three ranges (Low ≤120 HP, Medium 121–160 HP, and High >160 HP) using data from a CarPerformance.csv dataset. The chart uses d3.csv to load the data, d3.scaleOrdinal for color encoding, and d3.pie with d3.arc to generate SVG path elements. Labels are positioned using arc centroid calculations, and a legend appears in the top-right corner. The visualization demonstrates how D3 v7 transforms tabular data into an interactive-free categorical pie chart with clean SVG rendering.

Fork of Q1_DataViz_PiechartForCarPerformance

This interactive pie chart visualizes car performance metrics, allowing users to toggle between horsepower, torque, and highway MPG while grouping data by individual models or manufacturers. The visualization aggregates the dataset and limits top slices with an "Other" category for readability. Built with D3.js v6, it uses the `d3.pie` layout, `d3.arc` generators, and `d3.scaleOrdinal` for colors, with hover tooltips, animated slice transitions via `transition.attrTween`, and an interactive legend. The responsive SVG chart adapts its width to viewport size.
