This pie chart visualizes the distribution of cars by brand, where each slice's angle represents the count of cars for that brand. The chart is rendered as an SVG using D3 v7, with data aggregated from a CSV file via `d3.csv` and `d3.autoType`, then grouped using `d3.rollup`. Slices are drawn with `d3.arc`, colored using a Tableau10 categorical scale, and labeled with brand names. An interactive legend on the right lists each brand alongside its count, with color swatches matching the slices.

Fork of ICE7 Pie Chart

A pie chart visualizes sales figures for ten car brands, with each slice's area proportional to the brand's sales value and labeled in a side legend showing both the car name and its corresponding number. The chart renders as an SVG using D3 v5, employing the `pie()` generator to compute arc angles from the loaded JSON data, `arc()` to create the paths, and `scaleOrdinal` with `schemeCategory10` to assign colors to slices. The legend is built manually with appended rectangles and text elements, while numeric values are formatted using D3's `format()` function.

ICE-7 Pie Chart

This pie chart visualizes 2022 US auto sales by brand, showing each brand’s market share as a percentage and total sales in thousands. The visualization uses D3 v5 with `d3.pie` and `d3.arc` to generate SVG paths, while `d3.scaleOrdinal` assigns distinct colors to each segment. Legends display brand names, percentage values, and sales figures formatted with `d3.format`. Data is loaded asynchronously from a CSV file hosted on GitHub Gist via a helper function that imports `d3.csv`.

ICE-7 DV Pie Chart Car Sales

This pie chart displays 2022 US auto sales by brand, showing each manufacturer’s market share as a percentage and total units sold in thousands. The visualization uses D3 v5’s `pie` and `arc` generators to compute and draw SVG path segments, with `scaleOrdinal` assigning categorical colors. A legend on the right lists each brand with its percentage and sales volume, formatted via `d3.format`. Data is loaded asynchronously from a CSV gist using `d3.csv`, and the chart is rendered with SVG elements in a blank 960×450 canvas.

ICE - 7 Pie Chart for Car Sales (11508271)

This example visualizes top brand car sales in the USA for 2020 as a pie chart, with each slice labeled in thousands and a legend listing brands and their corresponding sales values. It uses d3.csv to load the data from a remote CSV file, then d3.pie and d3.arc to generate the chart’s paths, while d3.scaleOrdinal assigns colors to slices. All rendering is done via SVG, with text elements placed using arc.centroid for slice labels and a custom legend built from appended rectangles and text.

ice7_task2_1

This example shows the distribution of car brands in a dataset as a pie chart, with each slice labeled by brand name and its percentage of the total. The visualization loads data from a remote CSV file using `d3.csv` with `d3.autoType`, then aggregates counts per brand via `d3.rollups`. It computes slice geometry with `d3.pie` and renders the arcs using `d3.arc`, applying a categorical color scale with `d3.scaleOrdinal` and `d3.schemeTableau10`. A manual legend lists the brands, using SVG groups and rectangles.

ICE 7 Pie Chart

This visualization presents a pie chart of top car company sales by price, with each slice labeled with its value and accompanied by a legend listing the corresponding model names. The chart uses D3 v5 APIs including `d3.pie`, `d3.arc`, and `d3.scaleOrdinal` to generate the segments and map categorical colors, while the legend is built manually with SVG `rect` and `text` elements. Data is loaded from a GitHub Gist via `d3.csv` in a React-based setup, with the SVG rendered directly in the browser.

ICE 7 Pie Chart

This pie chart displays 2021 car sales by type, with each slice labeled by car category and its percentage of total sales. A legend to the right provides additional identification of the color-coded segments. The visualization is built using D3.js v5, which handles the data loading, pie layout, and arc generation. The code uses `d3.pie()` to compute the angles, `d3.arc()` to draw the slices, and `d3.scaleOrdinal` with `d3.schemeCategory10` for the color palette, with data fetched from a remote text file.

Actvity 7.1.1

This pie chart depicts the distribution of car models by brand, aggregated from a CSV file of individual car records. The visualization uses D3 v5 to generate SVG arcs, with an interactive tooltip revealing each brand's model count and percentage on hover. A legend displaying brand names, color swatches, and formatted model counts accompanies the chart, and the code explicitly uses `d3.pie`, `d3.arc`, `scaleOrdinal`, and `schemeCategory10` for rendering and color assignment.
