Outcomes

Chart_rendered (Priority: 1) — Error: CHART_RENDER_FAILED

Given:

  • chart type is specified
  • at least one data series is provided
  • data series has at least one data point

Then:

  • emit_event event: chart.rendered

Result: Chart renders with data, axes, legend, and tooltips according to configuration

Chart_empty_state (Priority: 2)

Given:

  • chart type is specified
  • data series is empty or all values are null

Then:

  • emit_event event: chart.empty

Result: Chart container displays an empty state message instead of blank space

Data_updated (Priority: 3)

Given:

  • chart is already rendered
  • new data is provided for one or more series

Then:

  • set_field target: data_series — Update data series with new values
  • emit_event event: chart.data_updated

Result: Chart animates to reflect new data without full re-render

Data_point_clicked (Priority: 4)

Given:

  • user clicks or taps a data point, bar, or slice

Then:

  • emit_event event: chart.clicked

Result: Click event emitted with the data point details for drill-down or linking

Series_toggled (Priority: 5)

Given:

  • user clicks a legend item
  • chart has more than one data series

Then:

  • set_field target: data_series — Toggle visibility of the clicked series
  • emit_event event: chart.series_toggled

Result: Series hidden or shown with animation, axes rescale if needed

Max_series_exceeded (Priority: 6) — Error: CHART_MAX_SERIES_EXCEEDED

Given:

  • series_count (computed) gt 10

Result: Only the first 10 series are rendered, user warned about the limit

Errors

Code Status Message Retry
CHART_MAX_SERIES_EXCEEDED 400 Maximum of 10 data series per chart. Additional series will not be displayed. No
CHART_INVALID_DATA 422 Data format is incompatible with the selected chart type Yes
CHART_RENDER_FAILED 500 Chart failed to render. Please check the data and configuration. Yes

Events

Event Description Payload
chart.rendered A chart was successfully rendered chart_type, series_count, data_point_count
chart.data_updated Chart data was updated (manually or via real-time stream) chart_type, series_count, is_real_time
chart.clicked A data point, bar, or slice was clicked chart_type, series_name, data_point, value
chart.empty Chart rendered with no data chart_type
chart.series_toggled A data series was shown or hidden via legend series_name, visible
Feature Relationship Reason
dashboard-analytics recommended Charts are commonly used as dashboard widgets
dark-mode optional Chart colors and grid lines should adapt to light and dark themes
accessibility recommended Charts need colorblind-safe palettes, ARIA labels, and keyboard navigation
internationalization optional Axis labels, tooltips, and number formatting depend on locale

AGI Readiness

Goals

Reliable Charts Visualization

Chart rendering system with bar, line, pie, donut, area, scatter, time-series, and heatmap types, responsive sizing, tooltips, legends, and real-time updates

Success Metrics:

Metric Target Measurement
success_rate >= 99% Successful operations divided by total attempts
error_rate < 1% Failed operations divided by total attempts

Autonomy

Level: semi_autonomous

Escalation Triggers:

  • error_rate > 5

Tradeoffs

Prefer Over Reason
accessibility aesthetics UI must be usable by all users including those with disabilities
