Learn Techniques to Improve Visualization
It’s possible to improve visualization with practice. This article describes some visualization exercises and tips that can help.
Visualization Exercises
Here are a couple of visualization exercises to experiment with.
Exercise 1
Before starting this visualization exercise, it might be a good idea to turn off your phone and put it in another room so it isn’t distracting.
- Find a small object, like a pen, cup, jar, or small toy. At first, use something that doesn’t have too much detail.
- Look at the object for about 30 seconds. Mentally trace the outlines and pay attention to the colors.
- Then close your eyes and focus on the afterimage, if there is one. Try to recreate the image in your mind.
- Repeat several times.
After you practice with a simple object for a while, try more complex objects, photographs, or artwork.
I had trouble mentally visualizing faces, so I would go out in public, look at someone’s face and then close my eyes and try to hold the afterimage in my mind for as long as possible. It took a long time, but after practicing regularly I eventually gained the ability to mentally picture faces.
If you can’t “see” anything mentally, you might want to look into aphantasia, which is an inability to form mental images.
Exercise 2
Another exercise that can help with visualization is to practice using a mind palace (also known as a memory palace). The act of creating mnemonic images and placing them in your memory palace is great visualization practice. It can also help you remember things better!
The memory palace technique involves creating an imaginary journey through a location that you know well. Then you mentally walk through that journey, stopping at fixed locations.
The memory palace could be somewhere like your bedroom or home, or even be based on virtual locations.
Regularly walking through your memory palace and visualizing the locations is great visualization practice.
For a full tutorial that uses mnemonics, see the memory palace page.

Please do not use all capitals because it looks like you are shouting.
Also, please do not double post in different threads, you will not get an answer sooner.
The JPG file is a bitmap image which cannot be converted into lines, arc etc. in ArchiCAD.
There may be bitmap-to-vectorial conversion applications on the market. If you successfully convert to vectorial then you just need to save it in DWG or some other format ArchiCAD will be able to open.
Traces
Traces visualizations let you follow a request as it traverses the services in your infrastructure. The traces visualization displays traces data in a diagram that allows you to easily interpret it.
For more information about traces and how to use them, refer to the following documentation:
- Tracing in Explore
- Tempo data source
- Getting started with Tempo
Add a panel with tracing visualizations
Once you have tracing data available in your Grafana stack, you can add tracing panels to your Grafana dashboards.
Using a dashboard variable, traceID , lets you create a query to show specific traces for a given trace ID. For more information about dashboard variables, refer to the Variables documentation.
Before you begin
To use this procedure, you need:
- A Grafana instance
- A Tempo data source connected to your Grafana instance
Add the traces visualization query
To view and analyze traces data in a dashboard, you need to add the traces visualization to your dashboard and define a query using the panel editor. The query determines the data that is displayed in the visualization. For more information on the panel editor, refer to the Panel editor documentation.
This procedure uses dashboard variables and templates to allow you to enter trace IDs which can then be visualized. You’ll use a variable called traceId and add it as a template query.
- From your Grafana stack, create a new dashboard or go to an existing dashboard where you’d like to add traces visualizations.
- Select Add visualization from a new dashboard or select Add Panel on an existing dashboard.
- Search for and select the appropriate tracing data source.
- In the top-right of the panel editor, select the Visualizations tab, search for, and select Traces.
- Under the Panel options, enter a Title for your trace panel. For more information on the panel editor, refer to the Configure panel options documentation.
- In the query editor, select the TraceQL query type tab.
- Enter $ in the TraceQL query field to create a dashboard variable. This variable is used as the template query.
- Select Apply in the panel editor to add the panel to the dashboard.
- Go to the dashboard Settings and add a new variable called traceId , of variable type Custom, giving it a label if required. Select Apply to add the variable to the dashboard.
- Verify that the panel works by using a valid trace ID for the data source used for the trace panel and editing the ID in the dashboard variable.
Add TraceQL with table visualizations
While you can add a trace visualization to a dashboard, having to manually add trace IDs as a dashboard variable is cumbersome. It’s more useful to instead be able to use TraceQL queries to search for specific types of traces and then select appropriate traces from matching results.
- In the same dashboard where you added the trace visualization, select Add panel to add a new visualization panel.
- Select the same trace data source you used in the previous section.
- In the top-right of the panel editor, select the Visualizations tab, search for, and select Table.
- In the query editor, select the TraceQL tab.
- Under the Panel options, enter a Title for your trace panel.
- Add an appropriate TraceQL query to search for traces that you would like to visualize in the dashboard. This example uses a simple, static query. You can write the TraceQL query as a template query to take advantage of other dashboard variables, if they exist. This lets you create dynamic queries based on these variables.
When results are returned from a query, the results are rendered in the panel’s table.
Use a variable to add other links to traces
The results in the traces visualization include links to the Explore page that renders the trace. You can add other links to traces in the table that fill in the traceId dashboard variable when selected, so that the trace is visualized in the same dashboard.
To create a set of data links in the panel, use the following steps:
- In the right-side menu, under Data links, select Add link.
- Add a Title for the data link.
- Find the UUID of the dashboard by looking in your browser’s address bar when the full dashboard is being rendered. Because this is a link to a dashboard in the same Grafana stack, only the path of the dashboard is required.
- In the URL field, make a self-reference to the dashboard that contains both of the panels. This self-reference uses the value of the selected trace in the table to fill in the dashboard variable. Use the path for the dashboard from the previous step and then fill in the value of traceId using the selected results from the TraceQL table. The trace ID is exposed using the traceID data field in the returned results, so use that as the value for the dashboard variable.
- Select Save to save the data link.
- Select Apply from the panel editor to apply the panel to the dashboard.
- Save the dashboard.
You should now see a list of matching traces in the table visualization. While selecting the TraceID or SpanID fields will give you the option to either open the Explore page to visualize the trace or following the data link, selecting any other field (such as Start time, Name or Duration) automatically follows the data link, filling in the traceId dashboard variable, and then shows the relevant trace in the trace panel.
