A Marimekko chart displays categorical data as a grid of rectangles where column widths represent the share of one category (cat2) and row heights within each column represent the share of a subcategory (cat1). The visualization uses D3 v3 with SVG rendering, nesting the JSON data by cat2 and computing proportional offsets to position rectangles. A linear scale maps cumulative sums to the x-axis and category proportions to the y-axis, while a category10 color scale differentiates cat1 groups. The chart includes percentage tick marks on both axes and tooltips showing raw values.

Marimekko Chart

This Marimekko chart visualizes product sales across US markets, using a mosaic layout where each column represents a market segment with width proportional to total sales and stacked rectangles showing market-specific values. The visualization employs D3's linear scales for x and y axes, with color encoding via the category10 palette. Data is loaded from a JSON file and processed through D3's nest and reduce functions to calculate segment offsets and proportional dimensions, while SVG rects are rendered with crisp edges for precise boundaries.

Gist 95392bf4a37344793786

This interactive bar chart displays comparative proportions across four categories, rendered as vertical bars (SVG rectangles) with a rotated axis label. Using D3.js v3, users can click and drag on any bar to resize it, with a semi-transparent background bar indicating the current editing area. The visualization distinguishes major and minor gridlines through separate `d3.svg.axis` configurations, while mouse events (`mousedown`, `mousemove`, `mouseup`) update bar heights dynamically based on cursor position. Hardcoded data arrays provide initial values, and all styling is applied via CSS classes.

Line Chart

This line chart visualizes monthly values for categories A through L, showing trends over time with a thick orange line connecting circular data points. The chart includes value labels and date labels for each point. Built with D3.js v3, it uses an ordinal x-scale, a linear y-scale, and SVG rendering. Hovering over a circle triggers a smooth transition that enlarges the point to yellow, reveals its corresponding value text, and draws a vertical orange line from the baseline, using D3's selection filtering and transition methods. The data comes from a local JSON file.

simple line chart from dataset

This simple line chart visualizes a small dataset of monthly values across seven categories, showing the trend of a metric over time. The chart encodes each data point as a grey circle on a black polyline, with the x-axis using an ordinal scale for category names and the y-axis using a linear scale for values. The code, built with D3 v3, parses dates from the dataset and renders the SVG with a fixed size. On mouseover, circles turn red, a dynamic value label appears, and a dashed guide line drops to the baseline; the final value is labeled at the line’s end.

Bar chart

A bar chart displays categorical values with six colored, semi-transparent rectangles. The visualization maps lettered categories (A through F) to numeric values, with axes labeled and gridlines rendered via D3's SVG axis API. It uses `d3.scale.ordinal` for the x-axis bands and `d3.scale.linear` for the y-axis range, while `d3.svg.axis` generates the ticks. Rectangles are appended and styled with `d3.scale.category10` colors, and the data comes from an inline array of objects with `x` and `y` properties.

simple line chart from dataset

This line chart visualizes monthly values from a small JSON dataset, plotting twelve data points from January to December 2016. The chart uses D3 v3 with SVG rendering, employing an ordinal x-scale for categories, a linear y-scale for values, and a dashed line path to connect the points. Interactive grey circles respond to mouseover by turning red and revealing hidden value labels and vertical dashed guides, which are initially styled white to remain invisible. The chart also includes monospace date labels beneath the x-axis.

Circular Heat Map

This circular heat map visualizes the relationship between four categories and twelve months, with each cell’s color intensity encoding the numeric value. The chart is composed of concentric rings, one per category, split into twelve angular segments for each month, creating a compact radial layout. Color mapping uses a linear blue scale from white to a dark navy (#01579b). Hovering over any cell triggers a tooltip displaying the exact month, category, and value. The visualization is implemented in D3.js v3 using SVG, with the circular layout emphasizing cyclical patterns in the data.
