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 "Striped Monogram" 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 1980s corporate identity manual. Crisp white paper, one corporate navy and gray, a bold condensed headline cut by thin horizontal white stripes like a striped company logo, and engineering-clean data marks.

Colors (use these exact values):
- Page: #FFFFFF.
- Corporate navy #1B2A6B for every mark, the title, the monogram, the baseline, tick marks, year labels and the footer rule. It is the only color.
- Label gray #6B7080 for the subtitle, y-axis labels and source line. Gridlines #DADDE4.

Typography (Google Fonts):
- Anton for the monogram (72px), the title (48px, all caps, 0.5px letter-spacing, stating the finding) and value labels (22px for the first point, 30px for the latest).
- Archivo for everything else: company name 14px 700 all caps with 4px letter-spacing; subtitle 16px 400 gray with measure, unit and period; axis labels 13px gray; category labels 14px 500 navy; source 12px gray; folio 11px 700 all caps with 2px letter-spacing in navy.

Layout:
- 52px side margins. Top left: a two- or three-letter monogram of the organization's initials in Anton, then a 2 x 60 px navy vertical bar, then the company name and a one-line gray descriptor stacked to its right.
- Title baseline about 184px from the top with the subtitle 30px under it. The plot fills y 262 to 496.
- Footer at y 546 to 580: a 3px navy rule from the left margin to about 832px, ending in a striped end cap (four 72px-wide navy bars, 2.5px tall, 4px apart) flush right, with the source line left and the folio right below.

Stripes (the signature):
- Apply a mask to the monogram and the title: 2px transparent horizontal cuts every 7px, running across the whole canvas so the cuts line up between monogram and title. Nothing else is striped.

Axes and grid:
- Horizontal 1px #DADDE4 gridlines at round values, labels right-aligned 30px left of the plot. A 1.5px navy baseline with 6px navy ticks under each category, category labels 26px below.

Marks:
- Line chart: draw the line as three parallel thin navy strokes that stay evenly spaced through every bend: stroke the same monotone smooth path three times, navy at 12px, then white at 7.2px, then navy at 2.4px, with round joins and butt caps. End points get 14px solid navy squares; label the first and last values in Anton. For several series, give each a different stroke count (three strokes, a single 3px stroke, a dashed 2px stroke) rather than a new color, and label each at its end.
- Bar chart: navy square-cornered bars about 55% of the band, each cut by the same 2px white horizontal stripes every 7px (a mask), with the value in Anton above each bar. Bars always start at zero.

Avoid: any second hue, gradients, shadows, rounded corners, stripes on body text or labels, and a legend when direct labels fit.

When you're done, render the chart and check that the stripes in the monogram and title line up, the three strokes stay evenly spaced on the steepest bend, and no label touches the line.
