Prompt for your coding agent

Paste it with your chart's code. It restyles your data to match this chart.

Restyle my chart in the "Dimension Bars" style described below. Keep my data, chart type, title meaning and units; change only the presentation. Use the charting library this project already uses (plain SVG if there is none). If the library can't express a detail, draw it in a custom layer instead of dropping it. Measurements assume a 960 x 600 chart; scale them proportionally.

Mood: a technical product spec sheet from a furniture maker. White paper, drafting-style dimension lines, one walnut ink for the data and crisp condensed model numbers.

Colors (use these exact values):
- Page: #FFFFFF.
- Data: #6E4B34 (walnut) for bars, the eyebrow and the mean reference.
- Drafting ink: #23262B for text, arrowheads, tag boxes, sketches and the header rule. Dimension and extension lines: #B7BCC3. Faint verticals: #E6E8EB. Secondary text: #6C727A.

Typography (Google Fonts):
- Libre Baskerville 700 for the title (25px, #23262B, stating the finding); Libre Baskerville italic 14.5px #6C727A for the subtitle and 11.5px regular for the source.
- Barlow Condensed for everything else: eyebrow and revision block 15px 600/500 uppercase with 2.2px letter-spacing; model numbers 16px 700 with 0.6px letter-spacing; product names 13.5px 400 #6C727A; boxed value tags 14px 600 with 0.8px letter-spacing ("16 WK"); axis numbers 14px 500; "WEEKS" and "MEAN 9.0 WK" 12.5px 600 with 1.2 to 1.4px letter-spacing.

Layout:
- 48px margins. Eyebrow and revision block at y 52, title at y 96, subtitle at y 124, then a 1.2px #23262B rule across the page at y 146.
- Rows 33px tall from y 170. Each row starts with a 34 x 22 px outline sketch of the product (1.3px #23262B strokes, round caps and joins, no fill), then the model number with the product name under it. Bars begin at x 262 and the scale ends at x 812.
- A title-block footer: a 0.8px #23262B rule, source on the left, a drawing number ("DWG. LT-07 SCALE 1 : 1 WK") on the right.

Axes and grid:
- Faint 1px #E6E8EB verticals at the tick values. The value axis is drawn as an overall dimension line in #B7BCC3 under the rows, with inward arrowheads at both ends, 10px ticks at each value and the unit word after the last number.
- A mean or target reference as a 1px walnut dash-dot line (6 3 1.5 3) with a small caps label at its top.

Marks:
- Bar chart: 12px tall square-cornered walnut bars from zero to the value. Every bar is dressed as a dimension callout: a 26px tall 1px #B7BCC3 extension line at zero and at the value, and a small solid #23262B arrowhead (7px long, 6.4px wide) just outside each end pointing in at the bar. The value sits in a boxed tag (46 x 20 px, white fill, 1px #23262B stroke) 14px past the end.
- Line chart: a 2px walnut line with straight segments on the same sheet; mark each point with a short #B7BCC3 extension line down to the axis, and put the latest value in the same boxed tag. Keep the dimension-line axis and sketches for categories where they make sense.

Avoid: fills other than walnut, rounded bars, shadows, gradients, color legends and heavy gridlines.

When you're done, render the chart and check that every bar starts at zero, the arrowheads touch the extension lines without covering the bar, the boxed tags never overlap the next bar, and the sketches stay light next to the dark model numbers.
