Comparing Mekko Chart Creator Templates: Which One Fits Your Data?

7-Step Guide to Building a Mekko Chart with Mekko Chart Creator

A Mekko chart (Marimekko) shows categorical widths and stacked values together—great for market share, product mixes, and revenue breakdowns. This 7-step guide walks you through building a clear, effective Mekko chart using Mekko Chart Creator.

Step 1 — Prepare your data

• Columns required: Category (x-axis segments), Subcategory (stack segments), Value (numeric).
• Arrange: Each row = one stacked segment within a category.
• Check totals: Ensure category totals (sum of Value per Category) reflect the relative widths you want.

Step 2 — Choose chart dimensions and scope

• Define x-axis categories (e.g., regions, product lines).
• Decide stacks (e.g., channels, segments) and whether to include percentages, absolute values, or both.
• Set date range if data is time-bound.

Step 3 — Import data into Mekko Chart Creator

• Upload CSV or copy/paste table into the data panel.
• Map fields: Assign Category → X, Subcategory → Stack, Value → Measure.
• Validate: Use the preview to confirm totals and segment counts.

Step 4 — Configure scales and sizing

• Normalize widths: Choose whether widths represent raw totals or normalized percentages.
• Axis settings: Turn on/off axis labels and gridlines per readability.
• Chart aspect ratio: Wider canvases help avoid cramped stacks for many categories.

Step 5 — Style for clarity

• Color palette: Assign distinct, colorblind-friendly colors for stacks; use consistent hues for the same subcategory across categories.
• Labels: Show category totals on the bottom and segment labels inside bars if space allows. Use abbreviations for long labels.
• Legends: Place legend top or right; hide if labels are self-explanatory.

Step 6 — Add annotations and interactions

• Tooltips: Include value, percentage of category, and percentage of total.
• Annotations: Highlight key segments with callouts (e.g., “+12% YoY”).
• Filters & drilldowns: Add interaction to isolate categories or reveal underlying data.

Step 7 — Export and iterate

• Export formats: PNG/SVG for images, PDF for reports, or interactive embed for dashboards.
• Review with stakeholders: Validate that chart answers the intended question (market share, composition, etc.).
• Iterate: Simplify if readers struggle—fewer categories, aggregated minor segments into “Other,” or use supplementary charts.

Quick checklist before publishing

• Data sanity: Totals match source.
• Readable colors & labels.
• Correct mappings: Category, Subcategory, Value.
• Helpful tooltips & legend.
• Appropriate export format.

Use this workflow to produce Mekko charts that accurately communicate relative proportions and compositions.
