Each serves a different purpose, * allowing you to explore your data and tell a visual story about it by combining geography and statistics. * Most cartographic visualizations fall into one of the following categories. * * Visualization type | Renderer * ----------|--------- * Location only | [SimpleRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/SimpleRenderer/), [HeatmapRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/HeatmapRenderer/) * Unique (typed) values | [UniqueValueRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/UniqueValueRenderer/) * Class breaks | [ClassBreaksRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/ClassBreaksRenderer/) * Continuous color/size | [SimpleRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/SimpleRenderer/) or [UniqueValueRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/UniqueValueRenderer/) with [SimpleRenderer.visualVariables](https://developers.arcgis.com/javascript/latest/references/core/renderers/SimpleRenderer/#visualVariables) * Multivariate | [SimpleRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/SimpleRenderer/) or [UniqueValueRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/UniqueValueRenderer/) with [SimpleRenderer.visualVariables](https://developers.arcgis.com/javascript/latest/references/core/renderers/SimpleRenderer/#visualVariables), [DotDensityRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/DotDensityRenderer/), [PieChartRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/PieChartRenderer/) * * ### Location * * In many cases, the user just wants to see where a set of features are located. Some examples might be * political boundaries, cities, buildings, rivers, etc. These are scenarios where you want all features * in the layer to have the same symbol. To accomplish this you would use a * [SimpleRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/SimpleRenderer/). * * The example in the screenshot below contains three layers; each uses a * [SimpleRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/SimpleRenderer/) to assign all features the same symbol. * The polygon layer represents states with no fill and a gray outline. The polyline layer visualizes * highways with bright blue lines. The point layer depicts cities as marker symbols with the same bright blue color. * * [![renderer-simple-basic](https://developers.arcgis.com/javascript/latest/assets/images/samples/1-simple-sym.png)](https://developers.arcgis.com/javascript/latest/sample-code/visualization-location-simple/) * * Read more on the [SimpleRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/SimpleRenderer/) page. * * ### Unique types * * [UniqueValueRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/UniqueValueRenderer/) allows you to symbolize features based on one * or more matching string attribute values. Unique values are typically differentiated with colors, * fill styles, or images to represent features of various types. * * In the image below, each line is symbolized with a different color depending on the jurisdiction * to which the highway belongs. For example, green lines are highways in the "Tampa District" whereas * red lines are highways in the "Central District". * * [![renderer-unique-lines](https://developers.arcgis.com/javascript/latest/assets/references/core/renderers/renderer-unique-lines.png)](https://developers.arcgis.com/javascript/latest/sample-code/visualization-location-types/) * * Read more on the [UniqueValueRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/UniqueValueRenderer/) page. * * ### Class breaks * * [ClassBreaksRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/ClassBreaksRenderer/) sets the symbol of each feature in a layer * based on the value of a numeric attribute. Symbols are assigned to classes, or ranges * of data. Each feature is assigned a symbol based on the class in which the value * of the attribute falls. In the example below, a [FeatureLayer](https://developers.arcgis.com/javascript/latest/references/core/layers/FeatureLayer/) representing * block groups is rendered with a [ClassBreaksRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/ClassBreaksRenderer/). Features where fewer * than 35% of the population have a college degree are rendered with a deep green color. Features * where between 35% and 50% of the population have a college degree are rendered with a pale green symbol. * The other features are similarly rendered based on the value of the attribute of interest. * * [![renderer-classbreaks-basic](https://developers.arcgis.com/javascript/latest/assets/images/samples/6-classbreaks.png)](https://developers.arcgis.com/javascript/latest/sample-code/visualization-classbreaks/) * * Read more on the [ClassBreaksRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/ClassBreaksRenderer/) page. * * ### Continuous ramps and multivariate visualizations * * Rather than manually creating several class breaks to visualize numeric data, you can depict more variation * in your layer using continuous styles. The color, size, opacity, and rotation [SimpleRenderer.visualVariables](https://developers.arcgis.com/javascript/latest/references/core/renderers/SimpleRenderer/#visualVariables) * allow you to do this in either a [SimpleRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/SimpleRenderer/), [UniqueValueRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/UniqueValueRenderer/), or [ClassBreaksRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/ClassBreaksRenderer/). * * The example below uses a [UniqueValueRenderer](https://developers.arcgis.com/javascript/latest/references/core/renderers/UniqueValueRenderer/) with an * [opacity](https://developers.arcgis.com/javascript/latest/references/core/renderers/visualVariables/OpacityVariable/) * visual variable to map predominant types and the strength of their predominance in relation * to other variables. * * [![renderer-vv-basic](https://developers.arcgis.com/javascript/latest/assets/references/core/renderers/renderer-vv-basic.png)](https://developers.arcgis.com/javascript/latest/sample-code/visualization-vv-color/) * * See [visual variables](https://developers.arcgis.com/javascript/latest/references/core/renderers/SimpleRenderer/#visualVariables) for more information. * * @since 4.0 * @see [Styles and data visualization](https://developers.arcgis.com/javascript/latest/visualization/) */ export default abstract class Renderer extends JSONSupport { /** * Authoring metadata only included in renderers generated from one of the * Smart Mapping creator methods, such as * [sizeRendererCreator.createContinuousRenderer()](https://developers.arcgis.com/javascript/latest/references/core/smartMapping/renderers/size/#createContinuousRenderer) or * [colorRendererCreator.createContinuousRenderer()](https://developers.arcgis.com/javascript/latest/references/core/smartMapping/renderers/color/#createContinuousRenderer).
