d3VIEW Features d3VIEW Platform Simlytiks

Simlytiks application in d3VIEW converts raw data into descriptive analytics using a variety of visualizers to facilitate a quick understanding of the data and to aid in decision making. Among the library of visualizers, one that belongs to the category of InfoGraphics is the newest addition called Image Annotator. It is one of the powerful visualizations in Simlytiks that helps associate data with meaningful images. Infographics has been seen as early as 25,000 years ago in the Serra Da Capivara caves of Brazil and it not new for humans to use data associated with Images to describe information. In this post, we walk you through the aspects of creating a visualization using ImageAnnotator using realistic simulation and non-simulation data to demonstrate its flexibility to work with a variety of data formats and types.

In the example below related to occupants and their safety, if we need to view key metrics pertaining to an occupant model such as Peak Head/Chest Acceleration or Peak Airbag Pressure or Volume, we can use an Occupant image and drag and drop the required key-performance-indicators (KPIs) which would result in an image as shown in Figure 1.0 below. As you see, now, we can visually associate the data to its measuring location and eliminate the need for time needed to associate the data to its location without this feature.

    • For the current illustration, let’s create a new visualization by clicking on Add Visualization button.
Figure 1.6: Image shows, ways of creating visualization: Add Visualization, Run Wizard available within the Add Visualization and Add Chart.
  1. Using the search window, search for Image annotator visualizer from the list of 40+ available visualizers.
Figure 1.7: With the help of Add Visualization, search for Image annotator visualization. Click on visualization name (Image Annotator) to add it to the page.
Figure 1.8: Image shows placeholder(b) for Image Annotator visualization and Input fields(a) for it.
  1. We can upload image for the visualization in 2 ways.
    • Click on Upload Image(a) as in Fig: 1.9 to upload an image from local system.
    • Click on Select image column(b) dropdown to choose image from a set of available images. This will be enabled if the dataset has any images in it.
Figure 1.9: Image shows uploading options from another dataset which has images.
Figure 1.10: Image shows, Upload button to import image from local system. Since this dataset does not have any image response, we don’t see other uploading option.
  1.  Now, we are uploading an image from local system using Upload Image(a) in Fig 1.10.
  2. Once the image is uploaded, provide name for the visualization. Ex: Annotator. Click on Accept button to create/add visualization to the Simlytiks page.
Figure 1.11: Click on Accept to save image to the Simlytiks page.

Once an image is added, Click and drag the required response to drop it on the image from left side panel. Please note that we can drop curve responses, scalar responses, Images and Key value.

Figure 1.12: Image shows different types of responses(Curve, Scalar, Image/Animations, Key value) that are available.
Figure 1.13: Drag and Drop responses from the Responses section available in the left side panel. Here the responses EngineSpeed and DewPointTemperatureL are dragged and dropped onto the image above.

Edit Responses’ settings

Once the required responses are dragged onto the image, we can change the settings for them.

  1. Click and drag response to change its position.
  2. Right click on the response to see more settings like, Edit style, Make opaque, Remove.
  3. Click Edit style to change settings like, Font size, Font style, Font color, Italics, Bold and underline for the response name.
  4. Click Make opaque to make transparent background or Opaque background.
  5. Click Remove to delete added response.
