Column charts - ✔Use to compare data across categories( requires categorical or
ordinal data, displays variables vertically)
Line graphs - ✔Use to display continuous data over time
Histogram - ✔Use to visually display normality ( normal distribution of
continuous/quantitative /frequency of data around the mean) for a set of data
points
Pie charts - ✔Use when you have one row or column of data and you want to know
how much one data point is in relation to the whole. Especially useful when
displaying portions or percentages
bar chart - ✔Similar to column charts but better to use when your labels are long (
categorical or ordinal data, there are spaces between bars and it is displayed
horizontally)
x-y scatter plot - ✔Shows the relationship among numeric values in several data
series, or plot two groups of numbers as one series of XY coordinates ( requires
continuous data)
donut chart - ✔Show the relationship of parts to a whole like a pie chart but can
contain more than one data series( can be continuous or categorical sections of a
whole)
Bubble charts - ✔Are continuous data that are arranged in columns on a
worksheet so that the X values are listed in the first column and the corresponding
Y values and bubble size values s are listed in adjacent columns.
Geospatial maps - ✔Visually depict the prevalence and occurrence of a condition or
disease geographically using polygons. The are 2 types of data used in mapping-
vector data and raster data
Raster Data - ✔A grid-based format for storing location-based data in a
geographic information system in which each equally-sized cell or pixel contains a
value that represents geographic data such as land.
Vector Data - ✔A format for storing location-based data in a geographic
