   ✅ Spec ID: histogram-basic

   Rationale: A fundamental visualization type for showing distribution of continuous data - distinct from bar charts (which compare categories).

   This is a new plot type, no duplicates exist.

   histogram-basic: Basic Histogram

   Description

   A histogram displays the distribution of a single continuous variable by dividing the data range into bins and showing the frequency (count) of observations in each bin. It reveals the shape of the data distribution, including central tendency, spread, and presence of outliers or multiple modes.

   Applications

   • Analyzing exam score distributions to understand student performance patterns
   • Exploring measurement data to identify quality control issues in manufacturing
   • Understanding customer age demographics for marketing segmentation

   Data

   • values (numeric) - The continuous variable to visualize
   • Size: 50-1000 observations recommended
   • Example: Heights, weights, test scores, transaction amounts, or any continuous measurement

   Notes

   • Clear bin edges with no gaps between bars
   • Readable axis labels showing frequency and value ranges
   • Consider appropriate bin count (too few hides patterns, too many creates noise)
   • Y-axis should start at zero for accurate visual comparison

   Next: Add approved label to merge this specification to main.

   🚀 Specification Merged!

   Specification: histogram-basic
   PR: #657 (merged)

   The specification is now in main and synced to PostgreSQL.

   ---

   Next: Add generate:{library} labels to start generating implementations.

   Available libraries: matplotlib, seaborn, plotly, bokeh, altair, plotnine, pygal, highcharts, letsplot

   Or use workflow dispatch for bulk operations.
