Versions

Agent access: @silverpoint/mcp, an MCP server that tells agents what silverpoint holds, the agent catalog, the silverpoint skill and a Claude Code plugin.

• A new package, @silverpoint/mcp: a Model Context Protocol server over stdio (npx @silverpoint/mcp) and stateless Streamable HTTP, hosted read-only at silverpointweb.vercel.app/mcp. See Use with AI (/docs/ai).
• Eleven tools: get_version, list_charts, get_chart, list_components, get_component, recommend_chart, generate_code (React, Vue, Angular and Reflex), search_catalog, validate_props, render_chart (the canonical SVG) and check_palette; the catalog, each chart and component, the diagnostics and the skill's guides as resources; the choose-chart and build-dashboard prompts.
• The agent catalog, agent-catalog.json, generated from the published types: the 60 charts and 38 UI components with their names, imports and props in the four frameworks, the grounds, palettes, timeline and the 25 diagnostics. This site publishes it at /agent-catalog.json, with /llms.txt and /llms-full.txt.
• The silverpoint skill (skills/silverpoint/) and a Claude Code plugin that installs it with the hosted server: /plugin marketplace add ecrespo/silverpoint, then /plugin install silverpoint@silverpoint.
• No change to the API of @silverpoint/react, vue, angular, core, grounds or fonts, nor to any render.

Palettes, 21 composed and overlay components (38 UI components in all) and the Knight Lab timeline, in React, Vue and Angular.

• Palettes on a new subpath, @silverpoint/core/palettes: six presets verified for WCAG contrast (silverpoint, sanguine, sepia, ironGall, verdigris, indigo), checkPalette, contrastRatio, PALETTE_PROPERTIES and nestProvider. palette on every chart, UI component, dashboard and provider; a nested provider or a prop overrides it field by field.
• Composed components (14): SpSurface and SpGlyph, the building blocks, and SpTable, SpPagination, SpBreadcrumb, SpAvatar (+ SpAvatarGroup), SpStatistic, SpDescriptions, SpTimelineList, SpCollapse (+ SpCollapseItem), SpEmpty, SpResult, SpTextarea and SpInputNumber.
• Overlays (7) on the platform's <dialog> and Popover API: SpModal, SpDrawer, SpPopover, SpTooltip, SpSelect, SpDropdownMenu and SpToast (in an SpToaster), each opened by a trigger you write; open + onOpenChange, v-model:open or [(open)].
• SpTimeline on @silverpoint/<react|vue|angular>/timeline: Knight Lab TimelineJS in the ground's hand, with @knight-lab/timelinejs ^3.9.13 an optional peer and a fallback when it cannot load.
• Two stylesheets beside styles.css: ui.css now draws all 38 UI components, and timeline.css skins TimelineJS (eras get a strip of their own below the axis labels).
• UI_COMPONENTS gains 21 rows with a family (ui, composed, overlay); UI_DEMOS gains 35 states; @silverpoint/core/timeline and TIMELINE_DEMO. Diagnostics SP023, SP024 and SP025.
• A link's href (SpButton, SpBreadcrumb) keeps only relative URLs and http, https, mailto and tel; a headingLevel outside 2..6 draws h3. Both warn SP017.
• No change to the rendered output of the 60 charts.

The second catalog: 27 new charts (60 in all) for distributions, comparisons, hierarchies, fields and networks, with drill-down.

• Distributions & comparisons (14): HistogramChart, EcdfChart, BoxPlotChart, ViolinChart, RidgelineChart, BeeswarmChart, LollipopChart, DumbbellChart, SlopeChart, BumpChart, ErrorBarChart, IntervalChart, DivergingBarChart and ConnectedScatterChart.
• Hierarchies & dimensions (8): WaffleChart, MarimekkoChart, SquarifiedTreemap, SunburstChart, TreeChart, ParallelCoordinatesChart, PolarLineChart and PolarScatterChart.
• Fields & networks (5): DensityBinChart, ContourChart, DelaunayChart, VectorFieldChart and NetworkChart (with the NetworkNode type).
• Statistics derived in the core: Freedman–Diaconis bins, type-7 quartiles, Tukey whiskers, Epanechnikov densities, a deterministic beeswarm packing, ranks for the bump chart. Each chart has a derived data table and one heightened mark.
• Owned layouts and engines: stratify, squarify (Bruls et al.), partition, the Buchheim tidy tree, marching squares, Bowyer–Watson with exact predicates and a seeded Fruchterman–Reingold force layout.
• Controlled drill-down on SquarifiedTreemap and SunburstChart: rootId in, onRootChange / @root-change / (rootChange) out. The chart keeps no root of its own, so a server render is the client's.
• Hierarchy charts walk as a WAI-ARIA tree by keyboard and announce each node's path, value and share.
• RidgelineChart requires groupKey, DivergingBarChart levels and ParallelCoordinatesChart dimensions.
• Recipes on a new subpath, @silverpoint/core/catalog; diagnostics SP020 (invalid hierarchy), SP021 (invalid statistic parameter) and SP022 (group too small).
• No change to the rendered output of the first 33 charts; each one-chart build stays within 0.1 KB.
• There is no 0.4 or 0.5 on npm: the packages went from 0.3.0 straight to 0.6.0.

17 UI components drawn as the charts are: buttons, inputs, tabs, cards, alerts and more.

• 17 Sp-prefixed UI components in React, Vue and Angular (ui/<name> subpaths): Button; Input, Checkbox, RadioGroup, Switch, Slider, Rate, Segmented; Tabs with TabPanel, Steps; Card, Tag, Badge, Divider; Progress, Alert, Skeleton.
• Hand-drawn frames by each ground's own inker: tone as hatching on silverpoint, as the weight of an exact white line on cyanotype. precision mode switches the inking off, as on the charts.
• A native control underneath every one (<button>, <input>, a <fieldset> of radios): forms submit natively, and the composites follow the WAI-ARIA keyboard patterns, with RTL arrows.
• Controlled or uncontrolled values: value/onChange or defaultValue in React, v-model in Vue, ControlValueAccessors in Angular.
• A new opt-in stylesheet, @silverpoint/grounds/ui.css, beside styles.css.
• React Server Component entry points for Card, Divider, Steps, Tag, Badge, Progress, Alert and Skeleton.
• UI_COMPONENTS (17 components, 45 states) on @silverpoint/core/ui and UI_DEMOS on @silverpoint/core/ui-demos.
• No change to the rendered output of any chart.

The Dashboard composition, linked charts, the cyanotype ground and a Tailwind preset.

• Dashboard and DashboardCell: a titled, responsive grid laid out by the core from plain data (columns, spans and row height per breakpoint), identical in React, Vue and Angular and server-renderable.
• Linked dashboards: link on a datum field (e.g. hour) and every chart marks the same item; onLinkChange / @link-change / (linkChange) report it.
• A second ground, cyanotype: a white line on Prussian blue where tone is the weight of the line. Nothing is hatched.
• Reference dashboards (kpi-strip, ops, mixed-spans) on @silverpoint/core/dashboard-demos.
• Demo datasets now honour every view prop; VolvelleChart's indexRing / indexValue turn the demo.
• New package @silverpoint/tailwind: a preset naming the --sp- variables as Tailwind tokens.
• Angular example app server-rendered with @angular/ssr.

• Packages are published from CI on every merge into main, through npm Trusted Publishing with provenance.
• No change to the rendered output.
