Provide a distribution / histogram chart for the cycle / lead time data, with bin size control and moment markers.

Acceptance Criteria:

• A. Provide histrogram chart w/ left vertical axis for frequency, and horizontal axis for cycle / lead time value bins.
• B. Show frequencies of data in aggregated bins as vertical bars (all juxtaposed).
• C. Provide control over bin size, with option for "auto" (smart built-in dynamic).
• D. Provide date range slider controls to filter data (just like Control Chart).
• E. Show colour-coded vertical line / marker for Geometric Mean, per a view-control checkbox.
• F. Show a colour-coded vertical line / marker for Geometric Median, per a view-control checkbox.
• G. Show two colour-coded vertical lines / markers for Geometric Standard Deviation above & below Geometric Mean, per a view-control checkbox.
• H. Show Lognormal probability density function (PDF) curve (fitted on same left vertical axis scale), per a view-control checkbox.
• I. Show Lognormal cumulative distribution function (CDF) curve (on new right vertical axis, with 0 to 100% scale), per a view-control checkbox.
• J. In summary footer, show Sample Size ("n"), Geometric Mean, Geometric Median, Geometric Standard Deviation, Min, Max.
• K. In summary footer, show Prediction Confidence Bound, with adjustable confidence level. (E.g., 95% confident that next work item will be complete within 15 days.)

Notes:

• Cycle / lead time is reasonably modelled with Lognormal distribution (or others), not likely Normal (as also evidenced by the existing logarithmic scale on the Control Chart's vertical axis).
• The Lognormal moments are the Geometric Mean & Geometric Standard Deviation.
