Arc Diagram | Irreducibly Human

Nodes arranged linearly with curved arcs above connecting related pairs. Arc height encodes the distance between nodes.

Area Graph | Irreducibly Human

A line graph with the area below the line filled, emphasizing cumulative volume or total magnitude over time.

Bar Chart | Irreducibly Human

Rectangular bars with lengths proportional to the values they represent. One of the most effective charts for comparing discrete categories.

Box & Whisker Plot | Irreducibly Human

Shows the distribution of data through quartiles. The box spans Q1 to Q3, the line marks the median, and whiskers extend to min/max (excluding outliers).

Brainstorm | Irreducibly Human

A mind map rendered as a force-directed graph. A central concept radiates outward to related ideas, which connect further to supporting concepts.

Bubble Chart | Irreducibly Human

A scatterplot extended with a third variable encoded as bubble size. Reveals relationships between three continuous dimensions simultaneously.

Bubble Map | Irreducibly Human

Bubbles overlaid on a geographic map, with size encoding a quantitative variable. Reveals spatial patterns in data.

Bullet Graph | Irreducibly Human

A compact alternative to gauges. Shows a primary measure (the bar), a comparative target (the tick), and qualitative performance ranges (background bands).

Gantt Chart | Irreducibly Human

A horizontal bar chart showing a project schedule. Tasks are plotted against time; bars show duration and overlap reveals parallelism.

Heatmap | Irreducibly Human

A matrix where individual values are encoded as colors. Reveals patterns across two categorical dimensions simultaneously.

Histogram | Irreducibly Human

Displays the distribution of a continuous variable by grouping values into bins. Reveals shape, spread, skew, and modality.

Illustration Diagram | Irreducibly Human

An annotated conceptual diagram using visual metaphor to explain a system or process. Spatial arrangement carries meaning; labels annotate.

Kagi Chart | Irreducibly Human

A Japanese chart type that filters noise by reversing direction only when price moves beyond a threshold. Focuses on significant turning points.

Line Graph | Irreducibly Human

Connects individual data points with lines to show trends over a continuous variable, typically time. Best for showing change and trajectory.

Radar Chart | Irreducibly Human

A spider chart showing multivariate data radiating from a central point. Good for comparing two or three entities across the same dimensions.

Radial Bar Chart | Irreducibly Human

Bars arranged around a central point, each extending outward. An eye-catching alternative to a conventional bar chart for cyclic or part-to-whole data.

Radial Column Chart | Irreducibly Human

Columns arranged on a circular axis. Variation on radial bar — good for showing cyclic patterns like time-of-day or month-of-year data.

Sankey Diagram | Irreducibly Human

Shows flow and proportional quantities through a system. Node width and link width encode the volume of flow between stages.

Scatterplot | Irreducibly Human

Maps two variables to x and y position. Reveals correlation, clusters, outliers, and the relationship between two continuous dimensions.

Span Chart | Irreducibly Human

Shows the range of values for each category with a line from minimum to maximum. A dot marks the average. Good for showing variability.

Spiral Plot | Irreducibly Human

Maps time-series data onto a spiral, making cyclic patterns visible. Each revolution represents one full cycle (year, week, day).

Stacked Area Graph | Irreducibly Human

Multiple area series stacked vertically. Shows both individual contribution and cumulative total over time.

Stacked Bar Graph | Irreducibly Human

Bars divided into segments to show both part-to-whole composition and the total simultaneously across categories.

Stem & Leaf Plot | Irreducibly Human

A textual display of data distribution retaining exact values. The stem groups values by leading digit; leaves show individual data points.

Stream Graph | Irreducibly Human

A stacked area chart centered on a baseline, producing a flowing, river-like shape. Emphasizes change over time across multiple categories.

Tree Diagram | Irreducibly Human

A hierarchical layout showing parent-child relationships as a branching tree. Radial or vertical layouts reveal depth and branching structure.

Treemap | Irreducibly Human

Nested rectangles represent a hierarchy. Area encodes quantitative value. Color can encode a second variable or group membership.

Venn Diagram | Irreducibly Human

Overlapping circles representing sets. Overlap regions show shared elements. Effective for showing logical relationships between two or three groups.

Violin Plot | Irreducibly Human

Combines a box plot with a kernel density estimate. The shape shows the full distribution — wider sections indicate higher density of values.

Word Cloud | Irreducibly Human

Words positioned and sized by frequency or importance. A quick visual summary of term prominence in a corpus — best for orientation, not precision.
